The artist at Pilgrim is Jerry Blumire. He is on Facebook as Jerry Blumire harpart. He’s lovely so you could contact him direct and have a chat. His artwork is beautiful. Generally speaking through, he doesn’t add paintings to finished harps, only to new ones. I enquired about having artwork added to a second hand Pilgrim Aldeburgh that I had just bought and it is because the soundboard would need to be stripped of any finish before it was painted. The harp would have to be taken part to do it so it would work out very expensive.
