This is for hedgehog enthusiasts everywhere: a woodcut bookplate, said by some to be the earliest in existence, featuring the name of a guy nicknamed "Hedgehog." Hans "Igler" Knabensberg had this plate on one of his treasured books sometime in 1450-1470. Igel is the German for that cute pointy animal. Perhaps Hans was prickly to be around, or spent a lot of time rolled up with his reading. He must have had a sense of humor though, because according to this page, the banner (written in Fraktur, the old German script) says "Hanns Igler, dass dich ein Igel kuss" (Hans Igler, that the hedgehog may kiss you - possibly a warning against stealing his book, but who minds a hedgehog smooch?).
