Best of the Litter, The

The Walker & Holtzapffel (Retail) Ltd., box-labelling helps to identify this beautiful plywood jigsaw puzzle as being from c1932, but I have not been able to identify the artist, whose signature is shown in close-up. Please get in touch if you can help. Thanks. Accurate colour line-cutting and the combined push-fit and semi-interlocking styles help to make a challenging puzzle to assemble.
