Air Union Jig-Saw Puzzle

Excellent puzzle from a painting by Charles C. Dickson of the Bleriot Rayon D'or passenger aircraft which was used on the Golden Ray service.
This promotional jigsaw puzzle advertises the plane as the Fastest Air Liner on the London-Paris Route. Interestingly the box also quotes SPECIAL VALUE. The price showing on the lid is 2/6, whilst the price on the box-base list shows 3/6 for a 150 piece aeroplanes puzzle.
The work of the same artist also features on this Salmon Academy Imperial Airways puzzle.
