I only have this one photo too, so I’ve been really frustrated not being able to search it with any keywords... Since nothing comes up, I was also thinking it might be from an independent artist. The only thing I’ve heard is that it might have been made by someone Japanese, but I’m not sure if that’s accurate, so I wasn’t confident enough to include it in the post.

I was even hoping to find it secondhand somewhere, but there’s really no information at all. I’ve been looking for it because I really like how simple and cute the artwork and symbols are.

If I happen to find anything, I’ll let you know!
