A Vancouver time travelogue brought to you by Past Tense.
The Retinal Circus was a divey rock club at 1024 Davie Street that opened in the summer of 1967. This was the Velvet's second performance there, and the last show before the venue shut down (as ominously suggested by the "Goodbye" at the bottom of the poster). For detailed listings of all Retinal Circus shows, see Chicken on a Unicycle.
