I bought this double cover treasury quite awhile back. Avoid the seller at all costs.
It was a legit double cover, not glued on the spine (as it should be).
The book was packed poorly and sustained damage, so I asked for a return.
After some back and forth, he agreed to take it back and I shipped it to him.
When he received it, he filed a claim saying I kept the second cover when I returned the book.
After some threatening, he admitted he lied (he had some excuse - I forget what). The next day the book was re-posted with new images of the book with both covers.
