Fantastic Inventory!
I have been creating a Grateful Dead collection for my little cousin, he's 36. I love the quality of this poster. It is in pristine condition. It was packaged well and shipped right after auction. I will definitely follow this auction house

Auction House is On It!
I've been buying eclectic Dead merchandise for my nephew who is also a Deadhead. I just happened upon this auction house, with amazing inventory. I can't wait to send these items for his next birthday gift. This house is incredibly efficient and I look forward to doing business with them again
