Unusual Beach Audience Black Hill Estate Sign Old Hereford RPC Postcard

zx772 Some research is needed for this most peculiar antique real photo postcard - All these people are in deck chairs on a beach but they are all fixated on something ahead of them gathered in large numbers - the location has a clue as there is a sign behind them which reads " Black Hill Estate Building Sites To Be Sold" (see top left) - Black Hill is in Hereford so I have added it to the title but a local historian must decide - Very good condition and surely circa 1908.
