Oh yes, the 'ol Blow yourself up ads. Seen in the back of every magazine in the late 60's and all through the 70's. I actually tried this service once and recieved my photo back in the cardboard tube. It was prehaps the grainest, poorly done thing I had ever seen. But, I did splurge for the 3x4' size and I'm sure that was a stretch. I think I sent a photo of me on my "banana seat" Stingray bicycle going off a jump.
