Here's the pin referenced by the uploader's commentary.

@Stickmin_Channel, you need to cite your sources. And by cite, I mean, place it in the "Source" field, not putting it in the damn commentary section. Even so, "Endless Summer" is definitely not the artist. I had no luck figuring out who the actual artist in question was (and while I did correctly figure out it was initially from the Chinese internet, searching Baidu just trapped me in a loop of dead Xiaohongshu links with no idea on the actual artist), but it is something you have to keep in mind if you're going to use Pinterest as a source.
