This is an extraordinary puzzle by Jumbo. The title is In the Library, by German artist Johann Hamza. In fact, it is just one of several paintings with the same title, depicting people reading books or documents in a library. We don’t know when they manufactured this puzzle, since Jumbo doesn’t usually indicate the year in the box.
The puzzle is COMPLETE (2000 pieces). The pieces are in excellent condition and the box is in very good condition as well., although it shows some minor shelf wear.
It measures 98 x 68 cm, 38.6″ x 26.8″. The reference number is 1748.
