The poster for the Avalon Ballroom's June 22-25, 1967 run is one of Rick Griffin's, with a Herb Greene photograph, and it advertised a meeting that the era's mythology would have loved to see happen: The Charlatans - the band whose 1965 Red Dog Saloon residency in Virginia City, Nevada is AOR's origin point - sharing a bill with Texas's 13th Floor Elevators, the acid-rock outfit whose 'You're Gonna Miss Me' and electric-jug weirdness made them psychedelia's wildest out-of-town cousins. The catch, and the day's quiet story: the Elevators are on the printed Family Dog poster (FD-67), but performance-history compilations record that they did not appear - consistent with the band's 1967 touring being mostly confined to Texas after a string of drug busts (their first documented Avalon date is February 1968, on FD-104). The run went on with the Charlatans, and at least one fill-in act, Emerald Tablet, played the closing night. It's a reminder that a poster advertises intentions, not guarantees - and that a date-page should read the poster against what the record says actually happened.

June 22 was the opening night of the run (a Thursday), which makes it a strong date-anchor: FD-67 is squarely about June 22, even where sources differ on the closing date (most catalog records say June 22-25; one show-list says 6/22-24 - the June 22 start is unanimous). The Charlatans at the Avalon in mid-1967 were no longer the scene's novelty but one of its founding institutions, playing the ballroom Chet Helms's Family Dog had made the Fillmore's gentler, more communal rival. The Elevators' absence - whatever its cause - left the night to the band that had, in a sense, started all of it two years earlier in Virginia City.
