I decided to move to trade only a couple of months ago and have gathered a small collection of books. I thought it would be cool to see other collections as well. Here are some facts about mine:
1. I buy new when I can, otherwise I look for VF to NM copies to purchase (I have a NM copy of Legacy)
2. My books are in chronological order per the earliest story in the TPB
3. I am purchasing the harder to find books first, which is why you don't see Year ONE, TLH, Knightfall, etc
Looking forward to seeing your collection!
