SMGQ-0018 6 pc lot Post cards sent back by member of the 328th infantry regiment

As near as I can tell, the soldier from the 328th infantry regiment must have taken these from a private residence or multiple residences while in areas like Czechoslovakia. They were already filled out in many cases, but he must have liked the pictures so he sent them back home. These ones have a mix of Czechoslovak and Austrian stamps i think.
