I was wondering if anyone out there could tell me where I might find a list of points to identify US Houghton Mifflin first edition/first impression dust jackets for all 3 books in The Lord of the Rings trilogy ('54, '55, '56). The books have been confirmed however I have not been able to find dust jacket information anywhere...
Many thanks in advance,

ps: wow 33 people viewed my post and no one has any suggestions as to how I might verify what I have? Yikes. Not even the name of a book I could buy with this information in it? Does it exist at all?
Thanks for anyone willing to assist!
