This is an old and rare puzzle by Educa. Since the box shows significant wear, mainly in the corners, the year of manufacture is not visible anymore. However, Educa probably published this puzzle in the early 80’s. The title is The Prophet Daniel, by Michelangelo. This fresco figure is on the Sistine Chapel ceiling.
The puzzle is COMPLETE (1000 pieces). The pieces are in excellent condition, although there are numbers in the back of the pieces. The box is not in very good condition, since it shows wear and scuffs.
It measures 68 x 48 cm. The reference number is 7752.
