Wednesday = Barksday!
More letters and photos from Bill Peckmann!
This time from 1979 and 1980.
[The letter above is actually from 1980 and not 1979.]
Looked through the files in my digital archive, where I store gems I find on the net and on eBay. And there I found a pencil drawing of the Queen of Sheba piece Barks mentions in his letter. :)
And for completeness sake, the finished painting as found on the net in a flickr gallery.
