The "Gold Elite Distributor" Edition of TRANSFORMERS: GENERATION 1 #1 1:25 Wraparound is signed by 4 members of the creative team (including Pat Lee, Rob Armstrong, and Chris Sarracini) and comes with an Official DREAMWAVE Certificate of Authencity in sealed bag with DREAMWAVE Seal.
Though it isn't clear how many of these exist, each certificate is numbered. It's also unclear how Dreamwave used this issue as an incentive, but it's believed to be related to the number of copies of this issue were ordered for comic shops.
"Bronze Elite" and "Silver Elite" Distributor Editions of Transformers: Generation 1 #1 exist as well.
