So, as this fine seller makes quite clear, the spider is missing. You can see the attachment area in the middle-lower-right section. Beistle produced this set for three short seasons during the 1950s. Ultimately, I think they were unsuccessful because of what you see here - the attachment goes missing. As I point out on page 158, given the extra labor involved to attach something to a flat paper surface and the very real prospect of that attachment getting bent up or falling off, I feel Beistle personnel threw up their hands and said, “Uncle!”

Vtg HTF Dennison? Beistle? Die Cut Spider`s Web 1950's HALLOWEEN Made in USA
This incomplete diecut was produced by Beistle during the 1950s. It was one of a set of four they produced during the mid-1950s. Missing is the spider made from black construction paper. (The others comprising the full set can be seen on page 158.) As I write, "Having an item like this spider separately attached to a diecut is unusual. More labor is required and the chance for defects increases the risk of returns. This may account for the mere three season run this diecut enjoyed."
