Very nice, copy Taro90.
When did you hear that the name of the dealer's source was Crippen? Back in 1996 or recently? If you heard it back in 96 then it might indicate that one of the family members was doing the selling and not just the "renovators."
I told by the dealer when the news of the entire collection of the "D" copies came to the market in 2006. So, it was recently. When the collection first surface it was only called the "D" collection. No one at that time knew who amass the collection. The person who sold the collection to the dealer where I got the "D" books from back in 96, didn't give any info as to where he got the books from.
