Aluminum 35mm Film Canisters
My dad was a retail camera buyer for a local department store. Previously and immediately after high school he worked as a darkroom technician for a portrait studio and then a drug store.
In high school, he told me that #Kodak was phasing out its metal film canisters and switching to plastic. I immediately started saving the aluminum ones, and sometimes he brought me some from work when people left their film to be developed and printed..
Over the years, I’ve discovered special film types had colored canisters. Shown in image 3 Is a book of little stickers printed by @moo. Good times.
