I don't know a whole lot about this, but there are three versions of the 1949 Leaf Premium Ruth. This one, the light background, is in the middle in terms of difficulty. (Dark background is the most common, blue background is the toughest - please correct me if I am wrong.)
The paper is really thin so these are frequently found trimmed down or with lots of creases and tears.
