The drawing is number 41 of a series of 60 Lee is providing to support comics shops during the coronavirus (COVID-19) pandemic restrictions. Each winning bidder gets to choose the subject of the next in the series; Brainiac was chosen by the bidder who won Lee's sketch of Silk Spectre. Among the thumbnail images in the portrait are those of Wonder Woman, Swamp Thing, Cyborg, Krypto, Commissioner Gordon and Sgt. Rock.

The sketch is rendered with pencil, pen, ink and whiteout, and is nine inches by 12 inches. Bids for the piece topped $10,000 at the time of this post. The listing states 95% of sale proceeds will go to Book Industry Charitable Foundation, which supports comics shops and other independent booksellers with financial aid.
