??? – The Batman Magic Photo Kit

Did anyone out there ever actually own one of these? I pulled this ad out of an old Silver Age book and then did some perfunctory research on the web, but I wasn’t able to find much of anything about this “Photo Kit.” I’m just wondering what they heck it was. For some reason I’m picturing one of those PAAS Easter egg decorating kits, but with pictures. I’m likely way off base with that. Or maybe you could paste Batman and Robin onto family photos crazy-stalker-Single-White-Female-style. Again, I’m likely wrong.

What was it?
