King George V. 300 piece

This 300 piece plywood jigsaw puzzle is far less common than the 150 piece version but uses the same print, just cut into twice as many smaller pieces.
Also included in the box were a copy of the GWR pocket map and the "Loss of Memory" sheet. Both are featured in the Chad Valley Literature album.
