I have several photo's dated 1927/8 that have P.S.A. hand written on the front. I asked Mum on at least one occasion what it meant and she gave me a naughty smile. Anybody out there like to stab at a guess?

The family lived in Salford, Lancashire, so that could account for the "S". The activity they were involved with was walking so "Pedestrian" could account for the "P". However, my best clean guess is "POSH SALFORD AMBLERS". Got a better one? Leave it in the Guest Book.
