Yeah, you have to be an old-timer like me to have been around for those 70s Monogram releases.  They contracted with Shep to build dioramas of around a dozen kits and write the tips brochure.  Monogram didn't extend that feature, sadly.  But Shep took the content he wrote and later expanded it into his book, "How to Build Dioramas".  That's worth tracking down and adding to your library.

The patches were a feature of the "Classics" releases in the late 90s or so.  Monogram packaged the kits with the original box art and added those patches.  I don't know if it helped move more kits, but the patches are kind of cool, too.

If you search eBay for the original diorama sheets, some people offer them for some pretty steep prices, too.  I kept all of mine, fortunately.
