This is an original signed drawing Art Trading Card or ACEO miniature size 2.5 x 3.5 inches, that collectors on eBay enjoy.
It is graphite pencil with a light spritz of graphite sealer on it to keep from smudging.
As with all art, the scans and photos do not do art justice. The scanner picks up the slight texture to the paper which sort of darkens the white paper a bit.
