Vintage original illustration Mary Baker animal drawing Kangaroo Rat

Vintage unframed small original unsigned Mary Baker illustration on thick paper....labeled Kangaroo Rat in the top corner. Very detailed looks like mixed media graphite and maybe ink original drawing...not a print. Mary Baker was an animal illustrator for many published books. This piece is unlabeled and undated so unsure if it was actually used in one of her books. *Given this piece is graphite it will smear with handling so handle and display with care. Age wear with lots of tanning, little spots and marks around the edges...corner bends...old aged tape discoloration on the back. *Please note photos. See my other listing for more original Mary Baker animal art from the same estate collection! Size approx: 11.25 x 14.25 inch...total paper size 3.5 x 4.5 inch...image size *Please see shop policies before purchase. Thank you!
