Sunday Stamps-II suggested today Gardens or forests as a theme. I was unable to decide between two beautiful series, so I am showing both.
Lancelot Capability Brown
According to the Wikipedia: "Lancelot Brown (1716 -1783), was an English landscape architect. He designed over 170 parks, many of which still endure. He was nicknamed Capability because he would tell his clients that their property had "capability" for improvement."
Royal Mail issued a set of 8 stamps to celebrate the 300th anniversary of his birthday. I have received almost all of them. With a great variety of postmarks!
