BISMARCK, N.D. (AP) _ Rosie Gries made her first Avon sale in 1938 _ a 10-cent tube of hand cream. Now, at age 100, she's still ringing doorbells as the company's oldest salesperson.

``I feel like I did when I was 16,'' Gries said on her birthday Thursday. ``I don't feel my age. I can't believe it.''

Some things have changed _ she hires a driver for her twice-monthly rounds, and she doesn't see or hear as well as she used to.

Nonetheless, Gries (pronounced greez) has vowed to sell Avon for ``as long as I can walk.'' She has about 25 customers in sparsely populated Sheridan County in central North Dakota.

Gries has gained fame for selling Avon products for the last 58 years _ even making an appearance on ``The Tonight Show'' in 1986.

Others have sold Avon products longer, but Gries is the company's oldest salesperson, said Scott Reiman, an Avon division manager.

Reiman presented Gries with 100 red roses and a large jar of lemon drops at a birthday party attended by about 75 relatives, friends and fellow sales representatives at the Bismarck Civic Center.

Gries sums up her life as ``work and work and work and work.''

``Tomorrow starts a new day and then I have to start over again,'' she said.
