Bradshaw had his first drawing published in The Boy's Own Paper when he was 15 years old, and moved to the art department of the advertising agency. Three years later he became a full time cartoonist, with his work also appearing in magazines like Bystander (magazine), Home Chat, Sunday Companion, Tatler, The Sketch and The Windsor Magazine. He also worked for a while for the Daily Mail. Bradshaw so closely resembled the Prime Minister, Asquith, that people would doff their hats to him when he went for walks in the park.
