Lijnschooten, Jan Van (1875-1958). As he painted in the database I have not found .
Alas, not as a painting Default (see attachment).
There is obviously a pseudonym. I guess the artist's name has rarely encountered in the Hungarian , French ( only in the names of settlements ) and the Welsh language letter "ÿ" (Y with umlaut ). The presence of the letter "experts" ( in my opinion ) would have to recognize it. As an example ( to your picture it is unrelated ) - a famous Hungarian scientist, zoologist Lajos Megey (Méhelÿ Lajos, 1862 - 1953). Would you ask a question at the appropriate Hungarian Forum , for example, at http://www.kepafalon.hu/festomuvesz-forum.php
