We are unable to get things authenticated at this time. If you want us to get them done after the auction we are happy to hold onto them and get them taken care of as soon as travel is allowed. They are, of course, fully guaranteed to pass CAS authentication. Check is in a sleeve mounted to a piece of cardboard with a print of a pencil sketch by Robert Riger also in a leeve and mounted. Check is from Reynolds's company "Reynold's Petroleum"
