Discovered an artist I've never heard of, is he as good as I think it is?

Hey everyone, the other day at work I picked up a book that had a ton of this artists work in it. The artist? Alastair, whose born name was Baron Hans Henning Voigt and was born in 1887. I don't really have any background in art or art history but I think hes pretty tight. His drawings are often decadent in spirit and have the look of Art Deco. That was an excerpt I got from Wiki, so take that at your will.
