"In The 1920s And 1930s, Sheep Were Routinely Introduced Into London Parks To Keep The Grass Under Control And Reduce Mowing Costs"
"Shepherds competed for the privilege of grazing their flocks on Hyde Park, Kensington Gardens, Clapham Common and other pastures around the city. Sheep are like a lawn care multi-tool. As they cut your grass, they also aerate the lawn with their hooves and spread fertilizer in the form of urine and manure. Sheep don’t require gasoline and oil changes, and although they are certainly not maintenance-free, grass-fed sheep are a sustainable alternative to lawn mower."
It must be after 1945. It shows a policemen in Hamburg, Germany.
Those kind of uniforms are bought from the British to germany. Hamburg was in the british zone after WW II.
They used this kind of uniform till the early 80s in Hamburg.
