Bert’s black and white sketches of Hollywood’s leading artists would have numbered in the hundreds. Most would have been used in theatre or movie promotion, many would have been sold at charity events or given away. However, I’m yet to find what happened to his collection on his (1934) or his wife’s death (1945). There were no children to inherit his work and family on both sides of the marriage resided a long way away in Australia. Maybe a family member is in the know !
