Yes, it's a photo of butter. Fresh creamery butter.
The line "fresh creamery butter" sticks in my head from the girly-girl film Kate & Leopold (2001). It's a commercial tag-line for a fictional brand of breakfast spread touted within the movie.
This, dear JSVB readers, is an actual stick of fresh creamery butter. It's not much like the butter you get in a grocery store. This little gem set me back eight dollars a shot. For one thing, it's at least double the price of store butter.
The price is worth it. Real butter seems almost like the lightest and creamiest of cheese. It slices smooth and thin without making a crumpled-looking blob on the knife. It has a clean texture and smell, not oily like the storebought stuff. It spreads very easily and the taste, well, the flavour transcends normal butter the way puffy white clouds float over the dull earth. Difficult to put into words, but fresh creamery butter on a slice of bread just out of the oven, that's ambrosia.
My recommendation: same as the dairy farmers would tell you. If you can find butter direct from the creamery, then go for it, and you won't go back to the supermarket stuff. It's good for you, good for the economy, and good food all the way 'round.
