Big Top, The

Several series of Big Top interlocking cardboard jigsaw puzzles were produced, the earliest carrying Good-Win manufacturing detail, whilst later examples dropped this in favour of dedicated Bertram Mills branding. Whether all were produced by Good-Win is not known so I have chosen to feature them here in their separate album for now at least.
The Good-Win examples have a small inset of The Late Bertram W. Mills who passed away in 1938, so I believe these were likely produced from soon after this date, but that the series carried on through the 1940's and on into the 1950's.
An artist signature of Mills on some of the prints adds further interest to this promotional series.
Please let me know if you can identify a connection between artist and circus. Thank you.
