35mm film in a 120 camera (sprocket holes)

I used to make "sprocket hole" photos, by running 35mm film through a 120 camera. I invented it, but you see it everywhere now. If you can prove you made one of these images before 1992, I'll give you a framed picture of Angelina in Edinburgh. Anyway, this is the method I used, and may use again. The impetus was the usual, "poverty begets invention" story: my 35mm camera broke right after I bought 100 feet of 35mm film. I had no money, a lot of film, and a 120 Ciroflex camera I'd bought at the Sausalito Flea Market for $12. "I bet I can use this stuff to make some photographs... otherwise, I fail the class."

Cut down the 120 film spool right at each ‘window.’ Slice the 35mm spool at the ‘step.’ Everything fits perfectly, to let you put two 35mm spools into a 120 camera. One empty, one full.
