Going through another envelope of old photos, I found this one of me and my grandmother Sally at her kitchen table (well, with me on the table...) A note on the back says August 1958, which means I'm 3 years old here. Below is a version where I tried to better the faded colours somewhat in Picasa3 (my standard simple editing tool).
In my own early childhood photo albums nearly all the photos are black and white, taken by either my father or my grandfather, and developed at home. This may be the earliest colour photo print I've come across so far, and I'm not sure who of them may have been the first to experiment with putting a colour film into their camera for a change. (I know my dad also took slides sometimes, though, so perhaps it could also be a print made from a slide.)
