This set of three fold-out small cat decorations was made by Whitney. This Massachusetts firm, which closed in 1943, was diffident about marking their many wares. Nearly the sole way to identify a Whitney item is to train your eye to recognize their art. The way I did it was to closely examine Whitney postcards, all or nearly all of which are marked. Imagery appearing in their postcards often become table decorations. Whitney also used a very open, unadorned font that is easy to identify. (Jason Walcott, a famed font designer and fellow Halloween collector, may be able to shed light on the precise name of the Whitney font.)
