L' Aiglon (Ballet)

Stunning and very tricky, interlocking plywood jigsaw puzzle with 72 Whimsies, or figurals from a beautiful painting by the British artist Carlotta Edwards (1894-1977).
A Super-Cut puzzle entitled Giselle features another example of work from this same artist.
Many thanks to Jacques Vélu for allowing me to display this magnificent puzzle here and for supplying photographs and details.
