The 1st printing postcard was printed before the concert in two different variants.
1st printing A (see FME001-A) is a vibrant pink, orange and green design by artist Jimms Nelson. It was printed before the concert and measures 4 1/8" x 7".
1st printing B is a black and white design featuring a photograph of Richie Havens. A "#1" is in the lower left edge of the image. It measures 4" x 7" and was printed before the concert, presumably because the A variety is difficult to read.
