You are purchasing an ULTRA RARE and ULTRA ODDBALL circa mid 1970's Oakland A's multi player signed airline voucher.  This is an awesome vintage piece!  This is a from Northwest Orient Airlines Adventure Tour order form brochure.  Nor sure exactly what the item is.  Appears to be the cover off a travel brochure.  Paper measures 3 1/2 x 8 inches.  Typical paper stock.  Paper is signed by 12 total players.  The story I received with this piece was that a family member was on the same flight as the Oakland A's from Minnesota and obtained these signatures while on the plane.  Signatures include Bert Campaneris, Joe Rudi, Rollie Fingers, Ken Holtzman, Claudell Washington, Jim Holt, Dan Hopkins, Vida Blue, Jim Todd, Glenn Abbott, Sonny Seibert and Reggie Jackson.  Paper shows minor wear.  Signatures are in black ballpoint.  This is as unique of a signed item as I have had.  Signatures have a 100% money back guarantee to pass any third party authentication.  VERY RARE early A's item!  Buyer pays $5.00 shipping.  Shipping combined on multiple lots whenever possible.  MN residents add 6.875% sales tax.  Thanks for your purchases!  Please check out my Ebay store for more great items!
