This 1897 advertisement for Aspinall's Enamel shows that paint companies knew more than 100 years ago lead was toxic. Aspinall's Enamel was being promoted in 1897 as "...NOT made with lead and is non poisonous." Reprinted from: National Academy of Sciences, Measuring Lead Exposure in Infants, Children, and Other Sensitive Populations (Washington, D.C.: National Academy of Sciences, 1993), pg. 25.
