Certainly a new twist on the usual blue plaque. It made us laugh and had us scratching our heads. It just seemed rather odd, but even though my SIL commented on how funny it was that Black should have lived opposite the 18th century naturalist Gilbert White in Selborne we still didn't realise it was a spoof. Now armed with online research it's obvious when you add in Gilbert and Sullivan to complete the jape😄 Even though he never existed Mr Sullivan Black apparently is still capable of leaving some very droll comments on his own dedicated twitter account https://twitter.com/sullivanblack3?lang=en
I think I shall never tire of this bonkers stuff which finds me!
