This is a really great pop-up Beistle invitation produced during the 1920s. There is a second pop-up design that I've almost never seen for sale. Made in the early 1930s, it features a scarecrow rather than a witch. I've wondered why it is seen so rarely, and conjecture that maybe that design was never sold in boxed or enveloped sets, but instead just singly, as Dennison did with many of their designs at this same time. Readers, have you ever seen a boxed/enveloped set of the scarecrow pop-ups? (A single can be seen at the top of page 223.)
