A poster that tells us what?
My academic buddy Bryant Sentes send me this pic of a poster that I find interesting:

I tried to find an exact date for the poster -- listed as 1950s-60s where Bryan found it -- as it might tell us what era the mind-set indicates: was it shortly after (or before?) Roswell (1947) or a bit after the Mantell incident?
The use of UFO rather than flying saucer tells us (maybe) that it is from the 1950s.
Does anyone have a clue?
