binge-watching the Lou Grant show on Hulu I saw a Geico commercial that includes a dogs playing poker picture. I decided to find out where the original picture comes from.
Actually it was a series of sixteen paintings of anthropomorphized dogs, only nine of which actually involve a card game. According to Wiki the paintings were commissioned by Brown & Bigelow to advertise cigars. There's a web site dogsplayingpoker which shows all the paintings by the original poker-playing dog artist C. M. Coolidge.
