     DESCRIPTION OF THE PREFERRED EMBODIMENT 
     Referring now to the drawings for a better understanding of the invention, it will be seen that the display stand embodying features of the invention, and indicated generally at DS in FIG. 1, comprises a vertically extending, generally U-shaped article retaining member RM and a box-like, article supporting, base member BM, which may be formed from the unitary paperboard blanks RMB and BMB illustrated in FIGS. 2A and 2B, respectively. 
     As best seen in FIG. 2A, retaining member RM includes a vertical rear panel 10, having a pair of vertical inner end panels 12 foldably joined to opposite side edges thereof along fold lines 13, and a pair of vertical outer end panels 14 foldably joined to side edges of respective inner end panels 12 along fold lines 15. 
     In order to accommodate collapsibility of the stand, each of the three panels is divided into three panel sections by horizontal fold lines 17 and 19. Panel 10 is divided into sections 10a, 10b, and 10c; Panels 12 are divided into panels 12a, 12b and 12c; and panels 14 are divided into sections 14a, 14b, and 14c. Fold lines 17 and 19 may be scored or perforated to facilitate folding. 
     As best seen in FIGS. 1 and 2B, article supporting base member BM includes a front side wall panel 20, a pair of end wall panels 22 foldably joined, along fold lines 23, to opposed end edges of front side wall panel 20, and a pair of rear side wall panels 24 foldably joined, along fold lines 25, to rear side edges of respective end wall panels 22. 
     As best seen in FIG. 4D, rear wall panels 24 have overlapped end portions which may be secured to each other by an adhesive or by stapling, as indicated at 59. 
     Base member BM has a top wall which includes a top wall front side panel 30, foldably joined along fold line 31 to an upper edge of front side wall panel 20; a pair of top wall first and second end panels 32 and 34, foldably joined along fold lines 33 and 35 to upper edges of end wall panels 22; and a pair of co-planer, but separated from each other, top wall rear panels 36, foldably joined along fold lines 37 to upper wedges of rear side wall panels 24. 
     When the display stand is formed, the base member rear wall panel and/or the base member end wall panels may be attached by adhesive or stapling as desired (not shown in the drawings) to the retaining member rear wall panel 10c and/or the retaining member inner end wall panels 12c. By having the retaining member so attached to the base member, the base member will self-erect when the retaining member is unfolded, as referred to hereinafter. 
     An important feature of the display stand of the present invention is the provision of the internal base member supporting structure best seen in FIGS. 2B and 4D. 
     This structure includes a plurality of narrow support panels, which are all of the same height as the side and end wall panels. 
     These include: a first support panel 40, foldably joined along fold line 41 to an inboard edge of top wall front side panel 30; a pair of second support panels 42, foldably joined along fold lines 43 to opposed side edges of panel 40; a pair of third support panels 44, foldably joined along fold lines 45a to adjacent side edges of respective panels 42; a pair of fourth support panels 46, foldably joined along fold lines 47 to adjacent side edges of respective panels 44; and a pair of fifth support panels 48, foldably joined along fold lines 49a to adjacent side edges of respective panels 46. Fold lines 41, 45a, 47, and 49a are parallel. 
     One third support panel 44 is also joined, along a fold line 45b to one edge of a connecting panel 38, another edge of which is foldably joined, along a fold line 39 to an adjacent edge of top wall first end panel 32. The other support panel 44 is foldably joined to top wall second end panel 34, along a fold line 45c. 
     Fifth support panels 49 are also foldably joined, along fold lines 49b to adjacent edges of respective top wall rear side panels 36. Also, as best seen in FIG. 2B, adjacent top wall panels are separated from each other by openings 51, 53, 55, and 57, which extend through the blank BMB and which also separate some of the support panels from some of the top wall panels. 
     As best seen in FIG. 4D one set of support panels 42 and 44, another set of support panels 46 and 48, and overlapping portions of panels 48 may be secured to each other by stapling, as indicated at 61. 
     After the display stand DS has been constructed and the retaining and base members RM and BM have been secured to each, other as previously described herein, the stand may be collapsed for purposes of shipping and storage, as shown in FIG. 3A. 
     When it is desired to open and erect the stand for use in the display of merchandise, such as the articles shown in FIG. 1, the panels of the retaining member RM are unfolded vertically, as shown in FIG. 3A, and then the panels of the retaining member RM are unfolded laterally or horizontally, as shown in FIGS. 3C and 3D. 
     As the panels of the retaining member RM are moved to the completely open position, as shown in FIGS. 1 and 3D, the base member BM will automatically self-erect, as shown in FIGS. 3c and 4A to 4D. 
     Not only will the side and end walls of the base member move to erected position, but the support panels will also move to erected position. 
     It should be understood that the invention provides a strong display stand capable of supporting a plurality of relatively heavy articles of, because of the base supporting structure, and also a display stand that can be collapsed conveniently, for shipping and/or storage, and yet can be erected for use very quickly, because of the self-erecting capability of the base member.
