That's what I thought. This work appears to be one of a kind. [He didn't doubt that it was his, honestly, but he had hoped he could learn more about... Well, anything if he could just find it here.] Compared to everything else, the style is pretty unique.

["Unique" was an understatement. Everything here seemed so... outdated and unpolished compared to the things in this sketchbook.

(Of course he thinks it's good, though. He didn't remember drawing it but he was sure he did.)]
