PROBLEM of the ALLIES
Dexterity Puzzle from World War I.
It mentions "Gas Attack" and has a Windmill which may well refer to the windmill at Pozières.
The name Yiddle is unexpected. Yiddle is Yiddish for Riddle or Plaything, which seems very appropriate; however it seems remarkable that a puzzle made in England at this time would have a Yiddish title though maybe it was because there were several popular songs including the word around this time.
It was advertised in 1916 as being produced by Hamleys and they included it in some of their Puzzle Compendiums.
