Advertising back of 7676

Discovered an interesting back overprint in this Oilette ‘Sheffield’ series 7676 post card view

@PTAsecretary thanks for the back, can you give me the front to I don’t put this in the wrong spot?

(there are a bunch of sheffield 7676’s)

Apologies for delay … this is the card with the advert on back:

@PTAsecretary no worries, back uploaded.
