DALLAS, TX.- Heritage Auctions’ May 5 Signature® Vintage Comics & Comic Art Auction, at the Fletcher-Sinclair Mansion in New York, will feature a newly recognized pedigree collection, the Twin Cities Pedigree, assembled by the late Gary Dahlberg of Minneapolis, MN. “It’s definitely the best Silver Age Marvel collection we’ve sold,” said Ed Jaster, Senior Vice President at Heritage, “and there’s no Marvel collection out there with better page quality.” “When I saw the Twin Cities books I was astonished by how nice they were,” said Paul Litch, Vice-President of the comic certification service CGC. “The collection runs the scope of Silver Age Marvels and DCs and goes all the way to some stunning Copper Age books – beautiful books, beautiful preservation. Once collectors see them, they’ll understand why we decided to give them a pedigree designation on the CGC label.&#148
