Oh man.. that's a great photo 'dedmans'.. What year would that be approximately. I'm sure someone like Eastney Dave would know. My dear old Dad would, that's for sure, but he's up with the Fratton Park crowd in the sky now..
I would guess about 1950. Based in Alton it could be that some local players are there but others are I am sure are pompey players but which and who I have no record.
If I ever get the time I'd like to research the early 50s period of Pompey FC as yours truly entered the world about then, and I really don't know enough about those days to be honest, and feel I should..
