This is an art poster created by the unit called "buddy." The title of the work is "[What love is]." It will be shipped framed. buddy consisted of Bunjo (@bunjo__), an illustrator from Fukuoka who has previously worked on artwork for Chilly Source's Pinoko, and shelboy (@shel__boy). (※See photos from the 4th image onwards) It seems that buddy is no longer active, so this is a very rare item.
