Here are the notes on this from the Sotheby's Auction the image was pulled from:
Dated June 27, at the Division Street Corral, with Lorrie Collins of the Collins Kids and The Big Beats Band, signed in blue ink center top Johnny Cash. This poster was a gift from Mr. and Mrs. Chas Celiliani, who has included a long handwritten note in pencil dated January 22, 1983 and partially reads: "We have many fond memories having you and your band here."
The original Division Street Corral opened in 1948 and was a dancehall and musical monument in Portland, Oregon where many big names from the early days of rock and roll played during the dawning of their careers, such as Bobby Darin, Paul Revere and the Raiders, and the Kingsmen (later known as the Statler Brothers, who would join The Johnny Cash Show in 1963). It was partially destroyed by fire in 1979 and rebuilt and reopened and is still in operation today. This is one of the earliest known Johnny Cash posters, featuring Marshall Grant and Luther Perkins, The Tennessee Two, which would become the Tennessee Three when W.S. Holland joined them on drums in 1960, further pulling Johnny Cash away from the country mainstream.
