This is a very rare puzzle by White Horse. The title is Columbus Discovers America, and the artist is Johan Herman Isings, although there is no reference in the box.
The puzzle is COMPLETE (1200 pieces). The pieces are in excellent condition, except for 3 pieces with very minor damage, as you can see in the photographs. The box is in good condition, with some wear, some small tape tears, and two tears on corners fixed with tape.
De Vuurbaak published an identical 1200 piece version of this puzzle, which most likely means both brands were related somehow.
