Ancient Citadel, An

This finely cut 528 piece plywood puzzle once again features the art of David Malcolm, a seemingly little known artist whose work features in several other examples from Holtzapffel's puzzle output.
If you can supply any further detail on him, please get in touch. Thank you.
This example features widespread colour line-cutting and the familiar combined cutting techniques of push-fit and occasional semi-interlocking pieces within a predominantly interlocking outer border. The box address of 61, Baker Street indicates this puzzle to be of c1932 or later, manufacture.
