Just picked up an original piece by Mike Trim, design artwork sketch for Captain Scarlet and the Mysterons, amazing bit of history from 1960s. The Angel Transporter design from Seek and Destroy, one of Mr Trims own favourites!
Thanks Chris, Mike was kind enough to write to me about it, said it was one of his favourites because original design and realisation were so close! Watched the episode recently, totally forgot the Transporter was bright yellow! Before Captain Black sets it on fire... The design is reproduced on the title page of his website
