A set of 2 cards numbered 7716 without images attributed to “JOTTER” (pseudonym of Walter Hayward Young) but the card titles put them in Cornwall rather than Kent.
There are existing cards numbered 7117 with images and with the same titles located in Cornwall but attributed to ARTHUR W. BRIDGEMAN:
THE MANACLE ROCKS THE MANACLE ROCKS - TuckDB Postcards
THE LIZARD DOWNS THE LIZARD DOWNS - TuckDB Postcards
Possibly need to wait for images of cards 7716 to be found to resolve?
