Photos with dates written on the back are few in the stash I have, but here are a few from that mystery year 1943. Remember that Walt’s little spiral notebook/diary ended in March 1943 with both Walt and Ruth arriving in Oklahoma City at Cimarron Field. These photos are dated 25 April, so they were probably still there when these were taken.
First, there are these three of Ruth walking toward the camera. Something is obscuring the upper left corner—Walt’s finger or the bill of his cap, maybe.
Then there are a couple of Walt.
Then they get someone to take a few of the both of them, trying to decide who should stand on the left and who the right.
