Got the same here in Sask. Dad could never afford to buy the photos the guys brought around in the early days (50s-70s) so its nice to be able to go back and buy the same photos now when I can afford them. So far I bought a 1959 pic of the yard in which I think I can see myself. Looking at the mid to late sixties pics too one of these days maybe.
