Those were 2 1/4x 2 1/4 negative size. You could blow them up a long ways. Full page in the yearbook was no problam. Hasselblad was a 4x4. That was huge. Remember the Kodak Instamatics with the flash cubes? Those negatives were about as big as your thumbnail. Teem that with a plastic lenz and you could get top quality prints. LMAO
