As to fleer retro.... has anyone noticed that most of the inserts are skybox inserts and not fleer? How then can it be fleer? It's just upper deck clearing house and trying to cash in on what was successful for other companies back in the 1990's - aside from MJ AU's and GU's, all of the big priced MJ inserts are from topps, skybox and Fleer.
Panini's license came into effect Oct 1, 2009. Upper Deck squeezed out Upper Deck, First Edition, Exquisite, SP GU and SP Sig before that date. Topps put out Topps (with Chrome as a product within a product) and bowman 48. Since that date, Upper deck has only had collegiate stuff while topps has done nothing basketballl wise.
