Little information is attached to these photographs, which appear to be from 1973-74. Around this time Airto was recording his albums Free and Virginland. He’s shown here with his band, which includes his wife Flora Purim. These two photographs were shot by Geoffery Hiller.
Negatives like this were used to print 8×10 promo sheets. Note how Airto’s last name is in red. Airto didn’t use his last name at the time so red tape was deployed to correct the typo (red reads as black in the printing process.)
