Did they provide the original air mail

You're referring to the famous Air Mail stamp!

Yes, the United States Postal Service (USPS) did provide the original Air Mail stamp, which was issued on May 6, 1918. The first Air Mail stamp was a 6-cent stamp featuring a biplane, and it was used to pay the postage for mail carried by air.

The Air Mail service was established in 1918 to provide a faster and more reliable way to transport mail between cities. The first Air Mail route was established between Washington, D.C. and New York City, and it was operated by the United States Army Air Service.

The Air Mail stamp was a significant innovation in postal history, as it marked the beginning of a new era in mail transportation. The stamp was also a popular collectible item, and it remains a sought-after rarity among philatelists (stamp collectors) today.

Over time, the USPS has issued many more Air Mail stamps, featuring a variety of aircraft and designs. These stamps have become an important part of American postal history and a symbol of the country's pioneering spirit in aviation.
