A beautifully illustrated hard cover book of folk and fairy tales from around the world, including Peer Gynt, Tovik Tomte and the Trolls, a story about African wind, the Twelve Seasons, a blue-beard type story from China, an Australian story about the breadfruit flower/tree, a Scottish story about a black bull & an Irish story about a mermaid.
Sounds like Andrew Lang’s “The Blue Fairy Book” originally collected from fairy tales around the world from the late 1800s to the early 1900s (the “Blue Fairy Book” and others in that popular “coloured fairy book” series, such as “The Red Fairy Book” seem to be a common source of fairy tale bookseller-stumpers!) Some of the stories from “The Blue Fairy Book” include The Black Bull of Norroway, Bluebeard, The Brave Little Tailor, Jack the Giant Killer, The Yellow Dwarf (a French mermaid tale), and many, many others, and the dozen or so books in the series pretty much cover fairy tales from nearly every populated corner of the world. I’m not completely familiar with details about the contents and don’t know for sure whether the contents match your description exactly, but I suspect “The Blue Fairy Book” is the one you’re looking for (if not some sort of abridged “best of” collection of highlights from the series).
