DALLAS – To collectors of vintage rock posters, KC Murphy’s assemblage, available April 16 at Heritage Auctions‘s Music Memorabilia Signature® Auction, features only the very best of the very best – 40 extraordinarily valuable, vaunted and crisp keepsakes from the Bindweed Press, near-mint memories pulled from a family friend’s famed printing presses when Murphy was just a little girl living in the wilds of Sonoma County. Her historic collection contains the totemic, valuable vestiges of a bygone Bay Area once ruled by the Grateful Dead, Janis Joplin, Quicksilver Messenger Service, Jefferson Airplane and their psychedelic brethren. Absentee and Internet live bidding will be available through LiveAuctioneers.
