Following the death in April of Vermont comic book retailer and collector Christine Farrell, her legendary collection is about to go up for auction. Farrell, who succumbed to a long illness at age 73, owned Earth Prime Comics and Quarterstaff Games, both located on Church Street in Burlington. She was an avid, lifelong collector of comics with a particular interest in the DC Comics oeuvre: She's believed to have at one time owned the entire run of DC, starting with comics published in 1938. Farrell was a tightly guarded person who rarely spoke to the press or discussed her collection. But now that rare collection, which includes first appearances in print of heroes such as Superman, Batman and Wonder Woman, will go to the highest bidders on the online site Heritage Auctions. It opens for online bidding on October 7; the auction itself takes place October 22 to 25.

According to van Dyke, not all of her collection will go to auction. Many of her friends and fellow collectors will be gifted individual items, and some will be sold directly through Earth Prime. "Most of the higher-end stuff is being graded and sold through Heritage," he said. "But with the rest, we're making a concerted effort to make sure they go to good homes. Chris loved these comics; it's definitely what she would have wanted." [content-1] Van Dyke is still running both stores, as well as helping with his former employer's estate. Details about the future of Earth Prime and Quarterstaff can't be revealed until the legal proceedings surrounding her estate are settled, he said, but he remains optimistic that they will continue to operate. "We're definitely trying to keep it going in the spirit of the way…
