Mystery Photo

This photograph is a bit of a puzzle.

Clearly a version of 1940 ‘photo-shopping’ has gone on. But what is it all about?

The inscription says “Thursday Oct 31st 1940 H.Petty ?”

Petty was a Littlehampton photographer and the building is said to be a Littlehampton or Rustington pub. A swastika seems to have been inked onto the fin.

Would love to know the story behind the image!
