Boys and girls had separate entrances to Medicine Hat school
Reminded me of the "Ladies and Escorts" sign seen in childhood.
Such signs were common in the fifties and sixties. The "Men's Entrance" led to the same place, as each pub only had one room. There was no "Ladies' Entrance." Proper ladies were meant to know not to go in there unescorted by men!
A vintage "Ladies and Escorts" sign hangs in Leo's Pub and Grill in Pincher Creek.
