Brochure in box explains "close time" protecting all birds in England during their breeding season. Unknown artist. Puzzle includes one mis-cut piece, probably replaced at the factory from stack cutting and now part of the puzzle's "provenance". it is not one of my 3 replacement pieces made for this puzzle. "Stack cutting" is when a cutter stacks 4 to 6 puzzles on top of each other, pins them together (leaving small nail holes), and cuts the stack. Problem is the blade bends so the pieces in the top layers won't necessarly match the pieces in the bottom layer. Normally, the pieces in each layer are carefully kept together and will fit together. But if one is mixed with its "counterpart" several layers below, it may not. See if you can find the mismatched piece here! This rarely happens.
