File talk:McKayandBlackCDC01.jpg

The photo has originally been published on page 199 in "History of dentistry in Colorado. 1859-1959" by William A. Douglas ((C) 1959 Colorado State Dental Association, Denver). The picture has been taken at Cheyenne Mountain in 1909 by Frederick McKay (who is not on the photo!) and shows G.V. Black and Isaac Burton and F.Y. Wilson, two dentists of Colorado Springs who worked with McKay on the "mottled teeth" problem. The original also shows an unknown woman on the right border, who has been partially cut off in the version uploaded to Wikipedia. --Trendley (talk) 19:19, 4 October 2011 (UTC)
