I took some shots of the Unicron I had everyone sign in this year's Botcon. If you'd like to see the signatures then check it out here... Unicron Signages.

I didn't have a booth. I pretty much walked around with it or had it in my bag and stuff. There were times when I didn't want to carry it... so I took parts and had people sign them... The only TFW2k'yers I know of who signed it are SuperMegatron, Alfy and Josh. There's even a video of me holding it... and singing. Xp http://www.youtube.com/watch?v=T5HTEnstuYE
