I don't have a date for the picture, but I estimate it's around 1940. George died in the summer of 1941, so it has to be prior to August 1941.
Here George (second from left) is posing with the male employees of the store. I wish I knew their names!
Here is Grandma (left, being hugged form behind) with the female employees of the store. Again, I have no names for the other women in the photograph with the exception of the very tall lady in the back - Velma Lawson.
Here's another year with the employees at Grand Lake. This looks like it late 1930's perhaps.
