An inflatable flag display includes a shaft having a hollow core and a sealed upper end. An aperture is located in the upper portion of the shaft and penetrates from an outer surface to the hollow core. A supporting base is connected to the shaft. A gas input connection is affixed to the shaft or the base and is in fluid communication with the core. An inflatable flag member is affixed to the shaft, formed of flexible material and has at least one inflatable chamber. The chamber is in fluid communication with the aperture and has an exhaust vent. A compressed gas source is in fluid communication with the gas input connection. A compressed gas modulator controls pressure or duration of gas flow, causing the flag to undulate. A variant includes means for rotating the shaft as the flag is inflated. Another variant includes an inflatable column replacing the shaft.
