"As best as I can remember, the graph paper came as a set with the binder and folders. I -think- my Mom might have ordered the set from the JC Penney or Sears catalogs or something like that, but I'm not sure."
An advertisement for these folders and binders ran in a few issues of
Dragon in 1981. The ad included a form to mail-order a binder for $.95 + $1.25 S/H, and it says the binder includes "a FREE 28 SHEET PACK of GAMERS GRAPH PAPER! An 80¢ VALUE!" (They put all that in upper-case, not me.)
The pack of paper in the ebay listing says it has 44 pages, so it's probably not the same pack mentioned in the advertisement. Still, it's completely possible that the department store these folders were ordered from put together a package set themselves. I recall holiday catalogs doing that kind of thing a lot in the 1980s.
