Mike theirs a great photo I saw at Disneyland taken in the 50's. I've been looking for it since, but haven't found it. Its a photo of probably 50-75 guests taking photos of the Disneyland characters.
Is I remember you could see everything from Argus to Zeiss being used, and the print was large and sharp.
I'll have to confess that I get some pleasure from seeing and identifying old cameras which appear in vintage photos, books and films. Pictures of them where they appear incidentally in the course of recording some social event seem especially nice.
