Narrative:

While holding 2 miles from show center; I in my aircraft and the DC3 came within 100 ft vertically of each other. DC3 was flying it routine to drop jumpers and was on its leg behind the air show area. While I had just came out of a turn in my racetrack hold; the last leg away from the track of the DC3. When I visually saw the DC3 I ducked under and he pulled up over. Two aircraft (or formation of aircraft) should not hold/fly at an air show in the same area; when both horizontal and vertical separation cannot be maintained. In this case where the ceiling was 1000 ft and neither plane could fly in this area below 1000 ft (or above due to the ceiling); and which is the minimum altitude over populated areas; not in the air show box.
