Horseshoe Curve

Horseshoe Curve (Altoona, Pennsylvania)

1 American Toleware stamp features artist Lou Nolan's painted detail of a black toleware coffeepot decorated with red flowers; purple forget-me-nots; and yellow, green and orange leaves, from the Winterthur Museum in Delaware. Curators at Winterthur believe that it was manufactured in Philadelphia between 1850 and 1875.

2 This stamp commemorating the 150th anniversary of Kansas statehood. In the foreground stands a type of efficient windmill pioneered in America during the mid-19th century, first made of wood but later out of metal (like the one shown on the stamp) and fitted with a tail, like a weather vane, to change the direction of the wheel relative to the wind. In the background stand five modern wind turbines that demonstrate continuity and the forward-looking nature of the modern Kansas economy.

3 For the Year of the Rabbit, which begins February 3, 2011, the art depicts kumquats, which are eaten for luck and given as special gifts.
