Not recommending you fly this three (3') H x five (5') W foot Flipping the Bird Flag from your beach house or a boat, but hey, that's your call to make.  Sometimes flipping the bird is exactly what needs to happen and a fine example would be flipping the bird to all the plastic in the ocean.  Made of 100% durable polyester it's lightweight, has been double stitched and uses two (2) brass grommets.  The black and white colors are sharp and the dye has been processed for UV (ultraviolet) fade resistance. 

In researching the history of flipping the bird, there are some funny instances and one in particular was when the USS Pueblo was captured by North Korea in 1968.  In several pictures post capture the crew was flipping the bird and when asked by the North Koreans why this hand gesture was in so many pictures, the Pueblo crew said they were displaying the Hawaiian Good Luck Sign, a cousin of the Hang Loose sign which is the thumb and pinky extended.  The North Koreans were oblivious for awhile, but once they figured it out they were none too happy and this did not bode well for the Pueblo crew.
