...'Q' was a wooden stamp that I found in the Brick Lane markets in London.
I was so excited when I found many large trays of typeface - wooden and 'copper' - what a find. They were rather expensive, about 4 to 10 pound each, but I bought about 60pounds worth so got a bit of a deal. About 4 months ago I washed and cleaned the 'copper' typeface only to discover that they were in fact copper coloured plastic glued onto weathered looking chipboard/cardboard. ---Ripped off!!! My daughter is still in London and she went back to the stall holder and told him the story - Don't think he believed her.
The 'R' is from the sign 'Riad' in Morocco which is like a guest house.
'S' is again from Gaudi's bronze doors on La Sagrada Familia in Barcelona.
The 'T' is from the sign 'Attic Rooms' - a pub sign in Surry. This fabulous pub had such low ceilings that even I had to duck - and I am only 5ft tall.
