Fred: Are you condoning Copyright infringement?
Bob you know full well I do not. My reply had to do with the feasibility of rendering a digital art file at a height of 72 inches. I would suggest that you, as the discoverer of the crime, have a responsibility to locate and contact C. Alexander, ascertain that he or she is the true owner and supply the details of the felonious activity to C. Alexander. If you have any problem making contact, you might want to contact a medium since he sold all his magic equipment and a supply of the poster in question in 1944 and left this earthly veil of tears in 1954. That may explain why one can get a 5,000 pixel version through the Library of Congress. You may find the
Wikipedia article of interest.
You are, of course, free to call out the OP of this thread, anyone else who viewed it or replied and most of all me. Don't be surprised, however, if some who read your post reach their own conclusions about you and your reasons for posting your accusation.
