Paul Murry - Finger Genius, 1975, WDC&S #416, page 8/8

It looks the original artwork for the whole 8-pager has survived.
Pages 1, 2, 3 & 6 has been sold by Galerie Laqua in 2007 and Heritage Auctions sold page #4 in 2015.

What is quite hilarious here is the link into real life and the economy: the oil producers are confessing how ordinary methods generate for them high profits ;-)
This story was done in 1975, after OPEC embargo in 1973 when oil prices almost tripled.In the last panel is quite hilarious goofing... ;-)

Look from the additional photo how tiny format is Disney's pocket books vs the artwork, also the original page layout is destroyed there.
