I always like browsing through old newspapers at http://chroniclingamerica.loc.gov. If you like classic pen and ink drawing, this site is for you. It takes some browsing, but it is well worth it.
A lot of well known illustrators got their start as newspaper artists. William Glackens, Henry Raleigh, Herbert Morton Stoops, Jeffery Machamer and Harrison Fisher to name a few. The San Francisco Call, the New York and Washington Papers has some of the best illustrations. Especially the Sunday Editions.
