Here is where the random story comes in. It wasn't random in that it is off topic, but more what happened. I took the two pictures to the counter and was making small talk with the cashier. Here is how the conversation went down.
Her: "These pictures are interesting aren't they?"
Me: "Yeah, I am guessing they are kind of old."
She picks up the picture, puts her nose to the back of it and inhales deeply.
Me: "I beg your pardon?" (As I tried to not let my jaw hang open in disbelief).
Her: "You can tell by the smell, they are from the 1950's."
Thought in my head: "Are you messing with me?"
I have to admit, friends, when I got into the safety of my own home with my treasures, I cautiously sniffed the back of one of the pictures. I am pretty sure I can guess what the 1960's and the 1970's smelled like and I know the 1990's smelled like Teen Spirit, but I am not sure what the 1950's smell like, but I smelled nothing.
