Abraham's Whale by Idan Shvartz.
This is a multi-step Sequential Discovery puzzle, full of complex and interesting steps to solve.
It is a limited edition of only 100 copies and this is number 67/100.
All my puzzles are kept in 40-50% humidity and out of direct sunlight, in an animal-free and smoke-free house.
Buyer pays for shipping, to be calculated after sale.
Happy Bidding!
