As a complete change of pace, I was recently received some scans of a small book drawn by Harold Tamblyn-Watts. The scans were sent by Michael Breeze whose family were friends of the Tamblyn-Watts's and are from a previously unrecorded book. I've not been able to find any information about it. The publisher, Rylee Ltd. was based in Birmingham and published from the late 1940s on, their output including a number of classic children's novels and stories in the 1960s and early 1970s, at which time they were using a London address. I'm reasonably sure this book dates from the late 1940s or early 1950s.
(* My thanks to Michael Breeze for the scans.)
