I've got a copy that looks like the regular Turtlemania (which is like the silver issue shown here, really, but without the S&N-ing right?). Wrapped around (but not stapled on) it is a yellow/gold paper wrapper that reprints the image from the front of the white paged book. Again, no signatures or numbering etc so it's not a silver or gold edition. Is that typical for all (some?) of the regular Turtlemania issues to have that extra yellow wrapper? I've searched ebay, comics.org and milehighcomics looking for a similar book but haven't spotted one.
Do you have a pic?
