What might work is the system that was used in nightclubs in the 1970s where you'd get a contact print of yourself and a friend at a table by the end of the evening. It was presented in a key ring holder which had a small magnifying effect so it seemed to be bigger. It was a bit like looking into a small slide viewer but with smaller magnification

By itself a contact print of a 35mm neg is so small as to be of no interest to most people except for maybe a head and shoulders portrait of a "loved one" that fits into a tiny frame.
