I recently got a 5th print of the WoG folio and it came with a promotional flyer for "Fantasy Figures by Minifigs.  Aproved by TSR for use with Advanced Dungeons & Dragons"

It's single sheet of paper printed on both sides and the same size as the Gazetteer.  There are 60 figures/sets listed each with a price and a note of their WoG setting e.g. Vale of the Mage, Iuz, etc.

I don't have one of these with my 2nd and 4th prints and was wondering if I have lost them, they only came with the 5th and later printings, or it was added by the original owner.

Any ideas?

My 1st printing had a Minifigs flyers as well; I think they were in all of the folio printings.  The list (sometimes not fully extended to the end of the line) can also be found in early issues of Dragon.

I'm pretty sure the Greyhawk figures ceased production sometime in late 1982 (or at least, stores ran out by then); I remember coming across a pile of overstock that was being sold at a flea market in Colorado Springs in the summer of 1983, and how happy I was to find them because I hadn't seen any since the school year before.   Also the WoG boxed set of 1983 didn't have a flyer or a miniatures line to support it.
