Once again, Twitter user @miiakira2017 shares More Transformers Generation 1 & Diaclone Early Concept Art.
This time we have some peculiar early designs. First, a possible idea for Transforming notebooks in Autobot and Decepticon versions.

You can check the full resolution images after the jump and then sound off at the 2005 Boards!
