Advertising Icons - Denver Opening - 1967

This was the first of the Family Dog shows in Denver, an experiment that would only last four months.  The "Dog" pulled out all of the stops for this first pair of shows, as Janis Joplin and Big Brother were the headliners, and Rick Griffin provided the artwork. This odd-sized poster whose horizontal treatment reveals very detailed pen & ink drawing of both commercial advertising icons of the time and inside references to other posters and characters of The Scene.  The title says, “Everybody is Good at Heart.”

The very detailed pencil art in the center features images of many famous advertising-related characters such as Elsie the Borden Cow, Mr. Peanut, Zig Zag Man, Smokey the Bear, Quaker Oats Man, Admiral Tobacco Man and other figures such as The Grateful Dead skeleton and roses along w/additional images of mushrooms, pumpkins, etc.  How many icons, mascots and references to other posters from the era can you name?
