I picked up these catalogues a few years back (I'm sure there were three - I'll probably find the other one next time I poke around in my old bedroom). Forum members may not be aware that Southebys and Christies held auctions solely for comics and comic art. Glossy pages with hundreds of reproductions of covers and original art pages. Oddly the artwork is printed with a grey tone which makes it hard to copy clearly - probably for a good reason ie people photocopying the material for use elsewhere.
