"[5] Thomas also created a record sleeve for Three Week Hero, an LP by PJ Proby and a rare cartoon cover for the obscure progressive rock outfit Rumpelstiltskin scripted by journalist/columnist Angus McGill.
[6] In the late 60s, Thomas designed a poster to promote a new range of cosmetics from Biba, the boutique operated by Barbara Hulanicki and her husband Stephen "Fitz" Fitz-Simon, at that stage situated at 124-126 Kensington Church Street.
[8] Big Biba closed in August 1975 after falling victim to a combination of over-ambition, in-fighting between the company's executives and the backers, property developer British Land and the UK's mid-70s economic recession.
The work for Big Biba drew a fresh set of commissions for Whitmore-Thomas, including Paul McCartney, who appointed the practice as in-house designers for his domestic and business interests, including the headquarters of McCartney's company PML in central London's Soho Square (complete with a recreation of his favourite Abbey Road studio in the basement), as well as recording studios in Sussex and on the Mull of Kintyre and private residences in London, Liverpool, Sussex and Scotland.
[9] As well as creating the livery for 25 buses on the Number 77 route, which passed Buckingham Palace in the Silver Jubilee year of 1977, the design practice serviced such clients as Danone, Guinness, Harrods, Lucky Strike, Pepsi Cola, Virgin, and Wrangler.
Thomas, who has also staged one-man shows at the Chelsea Arts Club and Dorchester Collections, is based in Deal, Kent, where he continues to produce artworks and make prints.
