Original 1968 Sparta Graphics San Francisco Jefferson Airplane, Grateful Dead, Moby Grape, Big Brother SUMMER OF LOVE

SAN FRANCISCO SUMMER OF LOVE April 1967 .
Saw this on a recent Estate sale in Dallas. It's a little rough but there are no paper loss, some small tears where another frame piece was stacked against it, in the garage. This is a large poster measuring 41 3/8 long x 31 1/4 wide on woven paper stock.
This was a series of concert / posters promoting Jefferson Airplane, Big Brother, Moby Grape, Grateful Dead, Family Dog.
Price was right, made a lower offer and they felt it was a fair offer and accepted it. It's mine now.
