No, not me. If you look at the tabs under the banner on this blog you will see one for the John Bowens who are not me on the Which JohnB? tab. There are several famous ones, even notorious in one case, but they are not this one.
Sadly the John Bowen who painted the most delightful watercolours has stepped away from his easel. Another one down. RIP JB. We never met, but I think that your work will ensure that you are remembered.
