I have three vintage Phillipsburg Kansas postcards for sale here. 2 are black & white and am guessing they're from around the 1950's. There's nothing written on the back of these 2.
The third card is a Phillipsburg street scene of State Street/Highway 36. A note written on the back states they ate lunch at the old hotel July 24th 1966. The "old hotel" was the Bissell hotel a block down the street on the right side.
If you have any questions feel free to send me a message and I'll get back to you as soon as possible. THANKS
