The j-pegs with 2007 at the front are the ones.
It took about a week and a half of spare time along with the help of my friend Bill and my nephew Trevor. I try and do this every year over a weekend, but now it takes so long I need help setting it up and taking it down. Most of the time my collection is in storage, however, I did buy a glass cabinet to rotate toys for show every month or so. This month I'll be putting all my Ultra Magnuses in there.
I don't have an accurate total yet, and a picture of my BotCon/convention toys is coming soon, as I'm not sure which ones I'll be keeping.
I loves my Obsidians! Forty-one in total!
