Biographical information on him is truly sketchy. A National Railway Museum publication in my library has the following:
"Born in London, he studied at Goldsmith's College and worked at the Waring and Gillow Studio. In 1930 he was commissioned to design four ceiling paintings for the Underwriting Room at Lloyd's and murals for Reed's Lacquer Room. He worked in naval camouflage during the Second World War. He exhibited at the Royal Academy and other galleries in London, and worked for the Empire Marketing Board, LNER, London Transport and several shopping companies."
And that's all I could find. The above blurb essentially deals with what he did starting at age 55.
The images below are of some of the poster art he did for the London and North Eastern Railway (LNER) along with a few others in the 1920s and 1930s. Some of his 1930s work for LNER is similar in style to that of Tom Purvis, a more critically acclaimed poster artist who I wrote about here. Most of his poster illustrations are made in more traditional styles. Regardless, they are skillfully done. They were also popular with the general public, if the criterion is sales of posters. Moreover, Taylor was the best-paid LNER poster artist.
