Heye manufactured this puzzle in 1998. The title is 2000 Years, by Marino Degano. There are three 8000 pieces puzzles by Heye: Berlin, New York, and 2000 Years. They are all quite rare, although 2000 years still appears every now and then.
This puzzle is NEW, with its original FACTORY SEAL. The box has a bump on the top, although the seal remains intact, as you can see in the pictures.
It measures 136 x 190 cm, 54 8/16″ x 74 13/16″. The reference number is 8401.
Heye published some years later two other similar puzzles by Marino Degano: Historia Comica – Opus 1, and Historia Comica – Opus 2. Even when Historia Comica – Opus 2 appeared later, it is, in fact, much more difficult to find.
