Does anyone have an idea of wallpaper came from? Ive searched high and low, but have had no luck. I love the wood/coffee cup combo

You can do the following:
Minimize any windows. Press Option+Shift+4. Then press space. Hover the cursor over the wallpaper, and click. Locate the screenshot on your desktop. Go to Google Image Search, search by picture, and upload the screenshot.
Wish you luck!
Better yet install the Safari extension Google Search by Image by Tonis Simo. Then you can initiate an image search from any pic you come across on the internet just by right clicking. And I tried this yesterday with no luck. Like the first response said, I think it's a custom wallpaper.
That's not required. If you right-click and "Google this Image" the search results will show the wood background without the coffee cup. There's no need to crop it out.Okay. That works as well, but let me clarify. When you use the key combination Option+Shift+4, and press space, it allows you to select certain objects. So, if you were to hover over an area with just the wallpaper, and click, you get just the wallpaper. The OP has to do this.
