Variations can still be found. Occasionally hand enameling was added to some patterns such as Zodiac or Bookmark. Colored stains add another variation. These were sometimes put in the recesses of patterns like Bookmark. For every collector there is a different style of collecting.
Some collectors stick with one pattern.
Some try to collect enough pieces to make a nice display on a desk. Others are looking to find every known piece in a particular pattern. This can get quite challenging after accumulating several pieces. Other collectors are looking for one item, such as a postal scale, stamp box or inkwell in every known pattern. Still others just buy what pleases them, regardless of the pattern.
