Looking for any information particularly photos of Ruspidge Corinthians football team which my grandfather Alexander (Alec) Hopson played for probably around the 1930's

Hi Sherrie,
have you seen these prior posts which mention the club ?
They confirm my first thought that old local newspapers might be your best source of info.

Googling shows an Ancestry member has researched their "Grancher" Alec Hopson (1908-1965), and has posted a team photo of his team Ruspidge Corinthians 1936-7. This is on a public tree so should be available to other Ancestry subscribers to view and copy, unfortunately I am not so can only aee this tiny preview, hopefully this link will help you. (I'm guessing this isn't your tree).

Which I now see is the same photo we're lucky enough to have on this site, the Ancestry tree suggests that Alec Hopson is "4th left middle row"
