Original 1st printing 8&1/2 x 11" concert flyer for Colours appearing with the Freudian Slips at the Matrix in San Francisco, CA from 7/14-16/1967. 
 
 Art by Rose, thin flat stock flyer is in near mint (A-) condition; just a few soft handling creases here and there and a sliver of  toning around the outer margin area, otherwise it is a mostly-clean example of this wild-looking mid-'67 Matrix flyer.
