Trying to find the TAMS journal would probably be rather difficult but I have reproduced it as a Word Document I can email to those who want it. There are no images of the varieties with the article (There aren't any in the Journal either.) I'll do some searches and see if I can't find some pictures of as many of the dies as I can.
