During the Second World War Rotholtz designed posters for the 'Make your money provide the driving power' campaign for the Post Office in 1943, and spent some time serving overseas. On his return to Britain he produced designs for trade-marks, press advertisements, brochures, posters and display units. His surname was sometimes spelt Rothholtz, and he often signed his work aR (The poster 'Be in the fashion, cover your hair', depicting factory chimneys and women in head-coverings is signed aR, and in 'The Poster in War-Time Britain', Art and Industry, Vol.35, No.205, July 1943, p.12, the poster is attributed to Rotholtz.)
