My moms house had that same Pepto Bismal pink wall tile in the bathroom too. With the plastic towel bar in between the parts that are mortared to the wall. Making them impossible to change short of sledge hammering them off.
Your door casing is also the exact same.
Moms house was in WNY, built in 1967.
Ours was built in 1963...when we moved in, it had bright red shag carpeting, an turquoise kitchen appliances!
