Jefferson Airplane - 1968 Original Grande Ballroom postcard

Description

This is an original and scarce 4x7 postcard, printed
before
the concert, advertising the November 21-24 shows at the Grande Ballroom, in Detroit, Michigan, featuring
the Jefferson Airplane,
Blue Cheer,
Tim Buckley, Terry Reid, The Stooges (w/ Iggy Pop), Frost, Wilson Mower Pursuit,
and
Caste.
There is NO poster for the event just this amazingly colorful postcard, designed by a trio of Detroit rock artists, Carl Lundgren, Jerry Younkins and Donnie Dope, featuring Airplane lead singer Grace Slick.
Print numbers for all 60's Grande Ballroom shows, for posters (where they exist), postcards and handbills were much smaller than their counterparts from the San Francisco scene.
Condition is gorgeous near mint with blazing colors.  The post card is on thin stock so this condition is a bonus.
Shipped secured, buy with confidence.  Thanks for looking!
