in 1925 Holt and Best merged to form their new tractor company, so familiar to people around the world: Caterpillar. Happy 100th anniversary to Caterpillar!

The first "1925 Caterpillar" was the Caterpillar Sixty, a rebranded version of the C. L. Best 60 Tracklayer

Tillamook celebrated 100 years of the Pig n Ford Model T races this month

Chrysler barely made it 100 years, it's only making a van. But it's still celebrating the past, and it did have a hell of a lot of successes to celebrate

Happy 100th birthday to the Goodyear Blimp! (one tire company became the restaurant critic, this other, became the live aerial coverage at major events in sports arenas and race tracks, proof that companies can become celebrated outside their genre)

The first non-military airship, Pilgrim, debuted in 1925 as the first helium-filled, non-rigid airship, marking the start of the Goodyear Blimp program.

the portable mooring mast built on a bus wasn't a short lived operation, it was maintained over decades, above, 1969, and below in back and white, debuting the messaging lighting system, was 1949. Both busses are labeled "Airship operations"

In 1946 and 47, Goodyear ordered 3 Clipper busses from Flxible.

as long as I'm posting about Goodyear, it turns out, they also own 10 other brands of tires, including Cooper, Dunlop, Mickey Thompson, and Avon, of the ones I've heard of
