Pink Floyd Knebworth Poster 1975
The flying bicycle parts were added at the printing stage after I had retouched the motorway print, and were nothing to do with me. On the lower carriageway were two cars, and one car on the upper carriageway that needed removing. Any lighter areas on the vehicles were darkened with photo Dye to match the road. Then with the grainy Airbrush using Windsor and Newton Permanent White Gouache, Windsor and Newton Sepia, Yellow Ochre, Paynes Grey and Lamp Black in varying forms, gradually sprayed out the cars. A final spray of Gum Arabic to put a gloss on the sprayed paint.
