I'm a big fan of markings and names myself. I really don't have much interest in owning Mile High/Church copies that aren't coded, as I love those markings and "Larson" so much
every g.a. collector i know prefers the markings. in silver, however, i think they differ. for example, those guys often have disdain for a dennis-signed winnipeg, seeking a "clean" copy instead. not me--gimme the name.
Given how distributor markings were so prevalent, I think GA folks welcome the markings as a part of the history of the book. While the markings are fine, I really enjoy the pedigrees with a history to them. Church, Okajima, Recil Macon, Crippen all have great back stories to go along with good-to-great quality books. While I love the Central Valleys for their beautiful white pages, the ones with the store stamps are the ones that I consider the coolest.
On the other hand, the SF/O'Reilly books have lost some of their allure to me given the increasing appearance that the story behind them was made up. They are lovely books and a joy to see, but knowing they might have been puffed up a bit with an urban legend diminishes the value I would place on them.
I agree with you Cheetah but no matter what the "story" is those books can be breathtaking. I've only got a few and they all have the stamp on back. I remember finding a few up in the bay area not noted. When I saw the stamp on back I got a little weak in the knees. Too bad about the bad press on them...
