Here's a sweet lookin old one. The back side has a 1cent stamp on it, so I'm assuming it is from 1951. I believe the post card postal rate went to 2 cents in 1952. And since the Last Frontier didnt open until 1951, i think it's pretty safe to date it as first year (1951) Cancelation doesnt show the year, just the city and time. Nice example of old Linen post cards.
