1959 Walker's Bourbon Ad featuring Jaguar Racer XK120? Magazine Ad

This original 8.5 x 11" magazine ad sponsored by Walker's De Luxe bourbon featured what I believe is a Jaguar XK120 vintage racer in the background, could be an XK140 I guess as well, but for sure it is a sexy Jag.  You decide if this goes in your Hey Bartender! collection or your Jaguar portfolio.
