Here are the two side by side. My copy is the second image (obviously, I guess).
This effort led to more research into finding photos of West of Ireland fishermen and Currachs. For the un-informed, a Currach is an ancient Celtic No Keel wooden fishing boat, formerly covered in animal skins (in tarred canvas these days). These boats, extremely lightweight and buoyant, are very effective in the rough Atlantic on the west coast, but hard to handle-usually with three or four oarsmen. Currach images in Irish painting scenes are somewhat cliched, but I have never done one. Now I am looking further for composing more paintings.
