Quite a few US publishers in the 1930's and 1940's put out books with jackets that had all four corners slightly clipped. You can find jackets in this style in regular trade editions with the publisher's price still there and in book club editions with no price.

There are some books where one corner of the dust jacket had a price in pounds and the other corner had a price in dollars, and a corner was clipped according to the country of sale. There are US children's books where the price in one corner of the jacket is for the trade edition and the price in the other corner is for the sturdier "library edition," and the jacket was always issued with one corner clipped.
