The card said "It's performance has been marred by bad luck". A quick google found a written report of it's first outing at the Doncaster air meet of 1909.
From Dallas Brett's "History of British Aviation 1908 to 1914":
....Captain Maitland tried unsuccesfully to fly a Voisin to which 'gyroscopes' had been fitted, whilst the comic element was safe in the hands of a Mr. Windham, who produced a monoplane of his own design and construction.
The meeting opened with a line up of the competing aircraft for photographing purposes. Mr. Windham posed himself gracefully on his machine, but he had gravely under-estimated its strenth. As the cameras clicked, there was a loud cracking noise and the Windham monoplane collapsed, depositing its proud owner on the grass. He took it away and repaired it, but at its next appearance it came gently into contact with a stationary motor car and instantly disintegrated once more. Fortunately it never got into the air.
From the following picture, it appears to be made of bamboo and linen, much like a kite would have been in those days. If it had got airborne, I think Windham would have been more famous for being the first British flying fatality!
