WW2 Butterfly Bomb Sign

The German SD2 (Sprengbombe Dickwandig 2Kg) butterfly bomb was a small 2 kg anti-personnel device capable of killing or causing serious injury. The early cluster bomb was used extensively on the Eastern Front but only a relatively small number were dropped on British towns and cities in East Anglia and the North East. They were first dropped on Ipswich in 1940, and later  dropped on Kingston upon Hull, Grimsby and Cleethorpes in June 1943, amongst various other targets in the United Kingdom. One of the hardest hit towns was Grimsby and the local area where approximately 3,000 were dropped and about 100 people were killed.
