Kay Jackman of Jitterbug Antique Toys & Collectibles rearranges antique dolls in a toys and dolls display that the firm provided for the Salt Lake City Library centennial. Included are tin Marx toys, left. The display, which will continue until March 29 at the Main Library, contains about 110 items, dating from the early 1900s to 1950. Seeing the display gives library visitors a "chance to step back into their childhood," Jackman said.
