Great Saturday Dances Psychedelic Concert Poster Chelan Washington 1960s

Description

An
original concert poster for Great Dances every Saturday Night at the Masonic Temple in Chelan, Washington (~120 miles east of Seattle) — expect late1960s and see the other auction for an Oregon 1967 poster that probably came with this one almost 20 years ago ….
Vibrant colors/design and native American imagery with cool psychedelic lettering and any information on these dances/bands would be appreciated.– printed by Foley Sign Company in Seattle, Washington
May The Sweet Baby Jesus Open Your Eyes And Shut Your Mouth
This is very similar to the words
probably created by Chet Helms and
used within the Family Dog logo  and starting in the logo with Wes Wilson’s FD5 Blues Project Avalon Ballroom April 1966 poster
and also included within Captain Beefheart’s
Safe As Milk
1967 album inner jacket
— and have to wonder if the native American Family Dog imagery and words inspired this poster art
Still deciphering if there is actually message/words in the two peace pipes on left/right sides — or just letters of some sort …
On quality cardboard 14×22 inches and in very good condition for its age with few tack holes in each corner, a torn lower left corner, tape stains on back at top and light moisture staining back bottom and some other general wear/handling  —  please see
pictures for condition and ask questions in advance if helpful. Will be mailed well packed with insurance.   Fillmore era 1960s psychedelic concert memorabilia
