Separate the 3 parts!
And assemble them again.
Patented in America in 1975, the somewhat swirled pieces of this puzzle by Eldon Vaughn must be disjoined and then put back together.
This is without a doubt among the most difficult of all puzzles.
The key word is “twist.”
Don’t use too much force…the pieces should just slide apart
