From Superman #206, 1968:

OK, I know it was a scam...but I really want to know how it "penetrates solid barriers."
Not to mention, I'm dying to know the native language of whoever wrote this ad copy, because it couldn't have been English. "Your Man From Uncle Spy Pen is a master of Precision Engineering"???
And hey, it comes "complete with simple how-to-use instruction booklet"! You'd think that would be standard, and not a "special feature" (rather like DVD's that list "interactive menu" as a special feature...'cause those NON-interactive menus make it kinda hard to play the damn movie...).
And gosh only knows how much those autographed pictures of Robert Vaughn and David McCallum are going for on eBay right now....
