Conference, The

A real gem amongst the Delta Fine Cut Range, this 1400 piece plywood jigsaw features a painting identified on the box label as D S Andeis, but actually the work of the artist Alex de Andreis, who is variously reported as being British (1880-1929), or Belgian (1880-1929).
This puzzle is shown on Page 8 of the Gamage's Booklet which can be found in the Literature section.

Puzzles of this size are very scarce, having been a costly luxury in the 1920's-1930's when they were made. 300-500 piece occur far more frequently.

Thanks to Jackie Van Noorden for allowing me to display the puzzle here.
