Lewis Evans is a watercolour artist from Hawke's Bay, NZ, who is listed as being active from 1915-41 (though there appear to be works from 1910-45). There were exhibitions of his works in 2020 and 2021 at MTG Hawke's Bay (mtghawkesbay.com). The gallery has both donated and purchased works of his.
I have acquired two early pieces dated 1913 (pond scene) and 1914 (bay scene). There was an earthquake in 1922 which changed the landscape which makes the works more of interest. There is a tear at the top of the 1914 piece which could be restored.
I am based in the UK and have no idea how the items arrived here. I could try to find out but haven't yet tried to.
