Henry Ernest Dudeney/Puzzles and Curious Problems/183 - Table-Top and Stools

Puzzles and Curious Problems by Henry Ernest Dudeney: $183$

Some people may be familiar with the old puzzle of the circular table-top cut into pieces to form two oval stools, each with a hand-hole.

Those who remember the puzzle will be interested in a solution in as few as four pieces by the late Sam Loyd.

Can you cut the circle into four pieces that will fit together (two and two) and form two oval stool-tops, each with a hand-hole?

The old solution was in $8$ pieces, but an improved version was given in only $6$ pieces in Amusements in Mathematics, No. $157$.
