I've scanned most of the Obak articles listed on the Old Cardboard site, as shown by Kawika in post 5 of this thread. The exceptions are the two OC eNews articles, which are about the T4 Obak premiums (very tough to find) and are online already; the 2005 Old Cardboard item, which is just a bio of Mark Obermeyer that mentions that he has a complete set of T212s; and the last article by Obermeyer in the March 2001 VCBC, because it turns out I don't have that issue of VCBC.
