Matti Valentin Huhta (February 14, 1880[1] – c. May 15, 1942), better known by his pen name T-Bone Slim, was a Finnish-American humorist, poet, songwriter, hobo, and labor activist, who played a prominent role in the Industrial Workers of the World (IWW).

[4] In addition to Matti Huhta, the nickname T-Bone Slim was also used by the miner William Vann,[5] the labor organizer Al W. McBride,[6][7] and various other unidentified individuals, often transients.

[3] Huhta worked briefly as a reporter for the daily News-Tribune in Duluth, Minnesota but resigned after an editor "misquoted him and balled up his article" about an Industrial Workers of the World (IWW) mass meeting.

[3] Huhta contributed numerous articles and songs to IWW publications over a period of twenty years and was widely regarded as one of the union's finest writers.

The IWW brought out the 38th edition in 2010 [13] and the Charles H. Kerr Publishing Company has other works by T-Bone Slim in its catalog.
