This is how the original Brabham BT50 decals looked like.
The Brabham kit came with both a hard plastic body and a Lexan body. Sheet A (above) is the sheet for the hard body. Sheet B (below) is the decals for the Lexan body. Second additional image is a scan of the decal from the reissue Brabham BT50 body set. Note the 'Goodyear' decals are missing.
