At work there was a guess the baby contest. 22 members of staff provided pictures of themselves to be guessed by others - a bottle of Prosecco to the winner. I actually missed out because I’m on leave, but I did contribute a photo. This isn’t my photo, but I thought it was a good one to celebrate the day!
I remember once the local summer theater had us guess the baby picture of the regular actors. My girlfriend and I worked together and guessed every one right. We didn't just try to look at the faces but also the style of the photographs and types of photographs. The backgrounds, etc. Lots of fun.
