Fast forward!

Any particular pizza box with proper focal length?
Nice.. a photo with pizza-z

Thanks for all your comments!!!

bobwysiwyg: I'm not sure about the bike name, but I believe it is a 50ccm Puch(?) - which used to be common in the 70s (or even 60s?).

papagene: the pizza actually wasn't that good. I defenitely prefer the homemade ones. But for a pinhole cam it worked.

blaze-on: this particular pepperoni pizza box comes with a focal length of about 20mm - which is rather wide on 4x5. Thus I extended it to about 40mm.
