Original 1st printing 17 x 22" silkscreen event poster, "Celebrate Union With All" (AKA the Seattle HELIX (underground paper)-sponsored "Chief Seattle Flower Potlatch and Isness-in"), a single day gathering of the hippie tribes/"be-in", held at Volunteer Park in Seattle on 4/30/1967.

 Designer unknown, image is featured on page 23 of  Scott McDougall's 2015 book "Split Fountain Hieroglyphics" (plate SFH 029).

 Medium-thick flat vellum stock hand-pulled silkscreen poster is in very good (B/B+) condition; there are a set of semi-flattened horizontal/vertical creases (one horizontal, two vertical), light creasing along the outer margin area, a few stray handling dings here and there, a slight curl to the paper from being rolled and a tiny stress bend or two hiding within the image area, otherwise fine.

 ULTRA-uncommon early Pacific Northwest Be-In item with a great psychedelic design.
