Dance of the Flowers

Quite superb 450-piece plywood jigsaw puzzle, bright and cheerful artwork and fiendishly difficult to assemble without a guide image. Took me ages!
The cut is almost entirely non-interlocking, with just a few interlocking edge pieces. Colour line-cutting abounds. The puzzle was cut by Dolly McDougall in 1961. The painting is unsigned.
