This is a pic from her web site, presumably showing her living arrangements. I could be wrong, but I don't believe there were VHS tapes or post-it notes back in the '50s.
Kodachrome was invented in 1935, but I don't think color film for snapshots was in widespread use during the '50's (color snapshots on desk).
From that photo...I didn't know we had VCR tape and pre-fab furniture back then. :)
