unused Halloween diecut nut cup with BLACK CATS, pumpkins, mice - Whitney??

This pleasing piece of ephemera was produced during the 1920s, almost certainly by Whitney. (Frustratingly, Whitney marked nearly none of their output aside from post cards. One has to look at Whitney's art from that time using post cards and items from their boxed sets to gain insight into their aesthetic. Hallmark produced items with a similar aesthetic at this time so one has to be careful with attribution. Hallmark typically cared about their product enough to mark much of their output.) There are at least six different designs from this set, maybe eight. Small paper is hotter now than at any time since I began collecting in 1988. It will be interesting to see if the BIN option is exercised.
