Can You ID This Skeleton?

I received an e-mail from a researcher the other day and he could use your help.

Here is his e-mail:

I am wondering if you can help solve an old mystery.  Do you recognize this old paper Halloween skeleton:

It appeared inside a Halloween card in 1970, so the skeleton is probably only 3 or 4 inches in size. It looks like an pre-made die cut paper product. I suppose it could also be a sticker, or cut out by hand from a greeting card or some other source.

Can You ID the Skeleton Pictured Above?

 

A similar die-cut skeleton was made by Dennison in the 60s:

Dancing Skeleton
