Kelly Freas Matrix Lady

Kelly Freas, the most honored science fiction illustrator of the 50's-60's painted the covers for Mad Magazine during its golden age (1958-1963).
This appears to be a sketch to try out an idea, a rare straightforward Kelly Freas woman. It came matted and sealed in plastic.
The signature is in the Mad Magazine style and may have been made long after the drawing. The distinct Kelly Freas style is much in evidence here, so much so that it would be unmistakable even without the pedigree and signature.
