Vintage ad from the back of a 1940s novelty & tricks catalog! Simply one of the coolest ads I have ever seen since I started selling ads!
Unfortunately - it was crumbling from age and I was not sure what to do so - I placed it on one of those "magnetic" photo album pages that are sticky. This page was newer and by a good brand ( It may have been Hallmark even) . It seems FINE how it is now. If this was placed in a frame and hanging up- 99.9% chance - NOTHING would happen to it. (I would place a piece or clear acetate film over it first -- I may have some around here that I can throw in for free. )
