Display Case

On of the neater Topps Gum pieces I have ever seen came across my radar recently, namely a bakelite counter display which held columns of Topps gum:

A small circular piece is missing at the right top (and possibly two are gone from the bottom) but it looks in fine shape otherwise. The gum tabs are described as the 1946 versions so the display looks to be a post-World War 2 piece.  Topps had patented a similar wooden display case about five years earlier so I guess this was the natural progression.

Can you spot the lone gum tab that is not Peppermint or Spearmint?
