Ok, I found my old Whitman list and added a few I have discovered in the past few days. This list is probably not complete and I don't have a current price guide to check but maybe Lighthouse, FD or someone else can add to this list of known Whitman variants. This list is especially weak when it comes to the DC Presents, Super Friends and New Adventures of Supeboy entries. Just for background this list is compiled based on various sources and although all are reliable a mistake or two may hae crept in especially since most or all variants didn't have the issue numbers on the cover. On to the list:
Action 481-483,485-492,495,496,498,499,501,503-508
Batman 306-308, 311-318, 320,323,324,326
Brave & Bold 143,145-147,150-157,159,165
DC Presents 1-4,10,11,12,14,15,19,21,22
Flash 268,273-276,278,283,286
Green Lantern 117-119,121
JLA 158,160-162,166-169,171-173,176,179,181
Legion 244-248,251-258,261,263,264,266
New Adventures of Superboy 2,5,6,8,31
Superman 321-323,325-327,329-332,335-345,348,350
Super Friends 13,14,15,16,20-23,25,32
