X-ray glasses?

When I was a kid I used to buy and read a comic book (weekly) called “Topolino“. It was the italian version of Disney’s comics.
On that comic book and others, in the last page there was a list of items that you could buy and get in your mail.
EVERY kid who was born between about 1960 and 1980 has seen those commecials. You could buy many things among which the most curious was a number of “secret agent tools”. The most famous was, of course, the X-Ray glasses. The commercial said that you could see in people’s pockets with those glasses.
They were also selling a number of other tools such as a tiny lamp, a tool to look through the door key-hole, etc.

Well, it might be a joke (just like the glasses) or maybe not, but it looks like the dream is still here, picturephoning brings us a reference about a new lens that everyone will want:
