Pair of original 1st printing 14&1/4 x 5" (appx.) 1967 promotional blank (Sunday) and postcard-backed (Thursday) cards for Thursday ("Crowds Bug You?") and Sunday ("Tribal Gathering") at the Avalon Ballroom in San Francisco, CA.
 
 Art by John H. Myers (both), images are not numbered images in the Family Dog/Avalon series, but they both date out to the Spring of 1967 and are designated in the Eric King guide as FD-670002 and FD-6700003.
 
 Medium-thin flat index stock cards are both in very good to excellent (B/B+ to B+) condition; each card has a couple of tiny staple holes in the outer margin area, along with a touch of handling, a pin-prick stain/light band or two and a few stray surface scuffs/bends hiding within the image area(s), otherwise fine.
 
 Nice little pair of early-'67 Avalon cards from the non-weekend nights at the ballroom.
