CARDINAL'S PORTRAIT INFORMATION LINK

Your question may be answered there but it wasn't specific enough -- if it's the value of the print, one site is selling it for $4.95 which is obviously a reprint, not the original 1944 commercial lithograph. The value of old prints which are not antique is what the traffic will bear -- there are also listings on E Bay for the print. One has to be cognizant of whether the copyright has expired on a print and publishers are reprinting the image helter skelter. That lowers the value of the original issue. It was not the usual marketing ploy of issuing these prints signed and numbered as if they were a fine art print executed by the artist. These days, that' a wide open field of marketing more often abused than not.
