"Optional" Leather Dust Jacket on 1911 First Edition Book

I had never run into this before: a 1911 1st edition book by Harold Bell Wright titled "The Winning of Barbara North" in what was an option when it was first published... a leather dust cover!

The book is not particularly rare ~ Mr. Wright was (and STILL is) actually one of the best-selling authors of all time (when sales are compared to the US population in his day). This is considered to be one of his better titles; the story of the loves of Ms. North in turn-of-the-century Imperial Valley California, but sold well over a million copies the first year. After some research, I found a website that spoke of the leather d/j-option on the first edition book. But so far I have not turned up another example of one on the market. Inside the front board pocket is a paper label that shows the cover costing an extra 70 cents! Considering that you could get a steak at Delmonico's for less than that kinda puts the cost in perspective....

And best of all, the book almost looks like it was picked up at the bookstore yesterday! Sweet~
