Yet more Franklin Institute postcards! This cool collection came in a few days ago and must have all been purchased at once, as they show what looks to be all from a particular period and all have a similar format. I’m guessing these are from around the 60s to 70s, likely leaning towards the mid to late 60s. Enjoy!
