Narrative:

Alleged operation from a NOTAM closed airport. Airport apparently closed at approximately the same time I left the facility. I was unaware of airshow status and made all the normal radio xmissions. Runway was not 'X'ed.' no supervision was apparent. Airport was notamed closed (I later found) at the approximately time I departed. It was a 2 aircraft show/demonstration. The incident would not have happened if a sign or supervisor or a person on the radio (122.9) CTAF had been active. No safety was compromised as I cleared the area with both aircraft in visual contact.
