例大祭おつかれさまでした！　例大祭公式でこんなスケブを作っていただいておりました。無事完売したみたいですありがとうございますごめんなさい。　5/30追記：今更公式ページ見たけど「フランとこいしがお姉ちゃんを一生懸命スケッチしている、可愛い絵柄のスケッチブックです。」って説明にくそわろた

Thank you for your hard work at Reitaisai! I've granted the honor to make this official Reitaisai sketchbook! It seems that it sold out completely, thank you everyone who bought it, and sorry for everyone who wanted to buy it but couldn't! P.S. 5/30: Just read this on the official site: "A cute sketchbook design, featuring Flan and Koishi furiously making sketches of their sisters on its cover", that made me ROTFL!
