Of those five records 1,2 and 4 were my consignments; the #34 pages. I have been quite happy with how they turned out. I hated to set them free but could use the money and I still have a fair bit of groo art even selling #34.
I think one reason some of the pages have done well is because Arba and Dakarba appear; they are the best supporting characters in the series IMO, and they are only in so many issues after all, particularly from the prime part of the run.
I will be quite curious to see how the cover does (will likely be in the next signature I imagine). Its a really wonderful cover with Groo, Sage, Rufferto, and Mulch.
