New stamps honoring a couple of "babes" - baseball star Babe Ruth and the bush baby, an endangered primate - are in this week's philatelic news.

A stamp honoring Babe Ruth has been released by St. Vincent Island in the West Indies. Postal authorities there announced that the stamp is part of a series which will, over a period of years, depict all the players who have been elected to the Baseball Hall of Fame.Former New York Yankees great George Herman "Babe" Ruth was idolized as the "Sultan of Swat" for his prodigious ability to hit home runs - a career total of 714. He led the major leagues in home runs 10 times, and twice tied for the honors.

The new $2 St. Vincent stamp bears a portrait of Ruth in his Yankee uniform. Beneath his likeness is his name, while vertically along the left side is "Elected to the Hall of Fame 1936."

The bush baby is featured on four new stamps issued by the east African republic of Tanzania.

The stamps were released in connection with the international omnibus issues that bear the logo of the World Wildlife Federation. The omnibus issues encompass almost 100 postal administrations throughout the world. At the same time, Tanzania also issued a souvenir sheet illustrating another endangered animal, the African palm civet.

The four bush baby stamps show the animal in a tree, ready to pursue its diet of insects and fruit. The denominations, in shillings, are 5, 10, 20 and 45. The souvenir sheet is 350 shillings.

These issues are available from your local dealer.

The U.S. Postal Service has prepared a special souvenir folder to commemorate the swearing in of George Bush as the 41st president of the United States. The event coincided with the 200th anniversary of the inauguration of President Washington.

Called the Bicentennial Inauguration Memento, the folder contains seven philatelic souvenirs - six stamped envelopes and a single post card. Each bears the postmark of a city in which the president or vice president was born or lived for some time.

The cover of the Memento has a reproduction of the presidential seal. The left inside panel has four canceled 25-cent Stars stamped envelopes. The cancellations carry the postmarks of Milton, Mass., Bush's birthplace; Greenwich, Conn., his boyhood home; Houston, Texas, his current residence; and Kennebunkport, Maine, his summer home.

The right inside panel holds two Stars envelopes bearing cancellations of Huntington, Ind., Vice President Dan Quayle's birthplace; and Indianapolis, Ind., his current hometown. Also included is a 15-cent Blair House post card bearing the postmark of Washington, site of the inauguration.

The center panel contains a color photo of the White House, plus descriptive text about the inauguration and the Memento contents.

The special folder costs $4.95 and is available at most larger post offices, at all Philatelic Centers and by mail from the Philatelic Sales Division in Washington.
