The summation of the two individual supply curves will generate the market supply curve for that product. Consider two wineries in the Paso Robles region.

The California Gold Rush (1848-1855) began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California.
Gold was first introduced in the United States when it was discovered on Reed Farm, North Carolina in 1799. The California Gold Rush, which is an important factor in the history of the United States, did not begin until 1848.
