Back in 1976 Floyd Gottfredson wrote an article about himself in "The Illustrator". And a few weeks ago the original cover was up for auction. The reserve was unfortunately too high for my budget.
A beautiful piece as you can see below. But $5000...
Browsing the net I also found this photo on Luca Boschis site.
(If I remember right.) This must be Gottfredsons reference photo for the painting. :)
I have the article from the Illustrator in my collection and will post it here as soon as I can find it. (I had it here two weeks ago, but now it's lost. Buried under a stack of paper I guess.)
