Interesting idea.
I also think it would be interesting to take a Title, and see if we can build a complete run using only slabbed pedigrees. You have lots of Avengers pedigree books, so we start with #1 (someone post a pedigree), move to #2, and so on.
Of course if Doug participates, he probably wouldn't need much help for many titles.
Or we can just starting have a post thread dedicated to each different pedigree. Just show as many as we can, which would be nice as we make start seeing difference between them (i.e. some have better quality of production, page quality, yellowing, exceptional gloss, etc.).
I'm a PEDIGREE ADDICT.
One of my (many) collecting fantasies is to own a copy of one book (like FF48) in several different pedigrees. But, that would take a long time to put together.
