The Happy Couple

Vintage plastic set square superimposed on an advertisement for the Olympus OM2 published in 1979.
The OM-2 was endorsed by Lord Lichfield, and the advertisement included several of his photographs of the rich and famous, presumably made using Olympus kit. I put a tinted 60 degree set square on top to encircle the abdicated King and his wife. That particular photograph was part of an exhibition at the Fox Talbot Museum in Lacock earlier this year.
