This might just be the hardest jigsaw I have ever attempted. Just sayin'.
If you want to be a masochist, it's the exquisitely beautiful Map of the British Empire in 1886 by Liberty Puzzles. It is actually very fun, but oh. so. frustrating. Do you like jigsaws? Would you like to be puzzling over this one with me? Have you ever used puzzles for map work or picture study? It works really well, because you spend so much time poring over the subject. Shame I've done more of this one than my student.
Right. Back to it.
