(x) "Jam" stressed sans caps - Optima (customised) {Dav}

anyone know what font this is?


'Optima', with a slightly adjusted 'J' and a stencilized 'A'?


I don't think that's Optima, although there are similarities.

Salzburg and Castle are also close, but no cigar.

Whatever it is, it started out as Optima Black. The skeleton and weight distribution matches.
