I had the Marvel Fanfare black Widow books for a few years. Sold them ages ago along with my run of NTT. Regret that now.
I've never sold any comics or art that I didn't regret selling later.
But (God bless the internet!) at least now you can read the same comics online in a number of online comics libraries.
