Sent to me by Dag Weiser, advertising
a series of shows from 27th April to 29th April, year most likely
to be 1978.

Many thanks to everyone
who has tried to help out with placing the year of this poster.
It seems that the most likely date would be 1978. Richard Kolke
may have spotted the clincher decinding this when he wrote:
I don't know if this
will help you pin down the date for the Boarding House gig, but
one clue that I have noticed on the poster is that tickets are available
at 'all BASS outlets'. To me, this would indicate that the show
is from 1978 as BASS outlets (or any of the other TicketBastard
precursors) were not around in 1972. I believe that 'Ticketron',
the first incarnation of these monopolizing, service-charging cretins
appeared in late 1974 or early 1975.
Many thanks to Richard and everyone
who helped with this.
