Scroll down to one of the months of Everydays in the period that’s covered on Behance (like this one—it’s everything until November 2016, plus that one in 2017). At the bottom of the page, you’ll see a Creative Commons license icon. Most of them only have the “Attribution” icon (which looks like a little person in a circle); some also include the “Non Commercial” icon (which looks like “$” crossed out).
