Wikipedia:Articles for deletion/Mego Sonny & Cher Toys
I have no personal interest in this type of "collectible".  However, a Google search for "Sonny & Cher" dolls +Mego shows coverage by the Chicago Tribune in 1976 and in a number of antiques and collectibles books.  Although these dolls may be little known in 2011, they were notable enough in 1976 that Bob Mackie designed the costumes.  This isn't an encylopedia of things in the 21st century, it is an encyclopedia of things that remain notable after decades, centuries and millenia, because notability is |not temporary
