Vintage 1930s Halloween Party Invitation Card #1

This pop-up witch invite was produced by Beistle during the late 1920s. They produced another pop-up design a few years later featuring a scarecrow. To my knowledge, the scarecrow design hasn't come up for sale in many years. Check it out on page 223. 

09/11 Update: This sold for less than expected - $44.
