This is a sports newspaper-style flyer featuring a special article about the Nishiura High School baseball team from the series "Ōkiku Furikabutte." I believe it was distributed at stores, but I've forgotten the details. (There's no mention of it being a magazine supplement, etc.) It's originally an A3 size, folded in half. (See photo 1) While there are no noticeable stains, please refrain from purchasing if you are sensitive to items that have been stored at home for a long time. Thank you for looking.
