May be able to identify the approximate year of the puzzle via its label. Rental puzzles were numbered chronologically by Betsy and the EMS team of artisans.
The earliest numbered puzzle in our records is #99. January 1988, likely just after starting the rental club. Believe Betsy may have started with #99, however, if any collector has a puzzle box with a lower number, we’d love to see a picture of it for further research.
Puzzles that were not in the rental club may have the year the puzzle was crafted noted on the box label.
