The puzzle is to separate the sets of Elk antlers then join them back together again.
This is a very difficult puzzle. At the end of the 19th century, Britain experienced a huge puzzle-craze and a version of this puzzle dates back to that time.
Size: Each antler is 45mm at its widest point. Presented on a red card inside a window faced brown card box (75mm x 115mm x 45mm) with solution enclosed.
