Re: Transformers comics
I can only reccomend one Graphic Novel (seeing as I've read it) with just G1 guys. Thats The Greatest Battles of Optimus Prime and Megatron. It collects certain issues from every TF comic from the 80s to now.
As for issues, for sure, by the old Marvel Series from the 80s. Its got up to 80 issues, and if you go to comic shops or shows, they are bound to have them.
Lee, Halladay, Hamels, Blanton, and The Vanimal
