When I was in college, I worked summers and holidays at Stansbury Photo in Reisterstown Plaza. The owners, Mr. & Mrs. Ehrenzweig, treated us boys as family. It was a pleasure to work there, and I learned a lot.
This photo is probably from summer 1970. The cheapest SLR we sold back then was the Praktica Nova 1B from East Germany. I noticed when I held it up to my ear and fired the shutter, it would go sproooiiiinnnggg instead of a more solid thunk like the Pentaxes, Canons, and Nikons. We loved making fun of the Pratica, and I had one of my comrades snap this photo of me being a wise-guy.
Ironically, many years later when I got back into photography, I bought and used several later-vintage Prakticas. The later models, from the 1980's, particularly the MTL models, were about equal to a middling 1967 Japanese SLR, which is to say, perfectly good.
