THE WORLD Series is over, but you've still got baseball on your mind, so take a slide over to the Portrait Gallery to admire some "Baseball Immortals." Sixty photographs taken by Charles Martin Conlon from 1905 to 1935 line the walls like so many trading cards.

Babe Ruth, Honus Wagner, Connie Mack, Lou Gehrig, Leo Durocher, Casey Stengel, Dizzy Dean and Ty Cobb. Practically every legend of early baseball except Casey at the Bat.

Grinning, dressed in baggy pants, old Yankee symbols on their shirts and caps, they're all-American boys, looking amazingly alike. Black faces are conspicuously absent.

Although most of the photos are portraits, the exhibit wouldn't be complete without Babe Ruth hitting a home run and watching the ball disappear, Christy Mathewson meeting a young fan and Ty Cobb sliding into third base, upending Yankee Jimmy Austin.

And, in this exhibit, when pictures don't say enough, labels pinch-hit with baseball lore.

Hired as official photographer for the Spalding Brothers sporting goods firm in 1904, Conlon took pictures of practically every major league player.

The prints have been developed from original glass negatives owned by "The Sporting News," this country's oldest weekly sports newspaper. The resulting high resolution gives these photos of baseball immortals a truly eternal quality.
