Looks like whoever it is took down the asset page, but they were claiming to have drawn the candy cane and gift boxes from this asset pack.

Hey fifthone. When I saw it it was already down, but thanks for letting me know about it. My sprites are under the CC4.0 license, this allows anyone to modify and commercialize the sprites in any way they want. However, it needs to provide credit to the author. I'll keep an eye on this artist's profile. :)
