Years ago, being a fan of @neilhimself.neilgaiman.com Sandman comic, I picked up his book Marvel 1602. Inside was a Bio on Neil and artist Andy Kubert. From that I learned about the Kubert school, to which I went after college. (1)
Unfortunately, I no longer have the volume in question - after I got my beautiful Sandman Omnibus editions(!), I passed my old TPBs along to new readers. It was either from Preludes & Nocturnes, or Season of Mists.
