I am looking for an OAG flight from the late 1960s or early 1970s. I've been watching EBay for about a month and realize that it may take a while to find one. Does anybody know of any other places where one could possibly find one? I would like to know where else to look, so that I can maximize my chances of finding on old OAG Flight Guide in the reasonably near future. Any advice or suggestions would be greatly appreciated. Thanks.
