White tub. Blue top.
The image on the tub features a building first made famous as the site of slave rebellion where slaves overtook, chained, and whipped their slavemaster. Later the building was used as a Union Army hospital during the Civil War where surgeons operated on thousands of wounded soldiers following a disastrous defeat at the Battle of Fredericksberg, Virginia. Poet Walt Whitman once described seeing a large heap of amputated legs, arms, hands, feet, etc. under a tree in front when he went there looking for his wounded brother.
