British Image restorationist, composer, amateur photographer and artist, and Wikipedian
As Adam lives in Britain, which makes it incredibly easy to acquire copyright in his works, he grants, if needed, an irrevokable license to use this work however you see fit. He requests attribution where possible, and realises that "where possible" means that that request is not legally enforcable. Adam Cuerden (ᎧᏃᎮᎸᏗ) 15:44, 16 January 2022 (UTC)
