The discoveries were not found on the road, but while browsing the Internet this morning. I found a reference to color photos made in Russia between 1909 and 1915. The dates are correct. They are fabulous. See http://commons.wikimedia.org/wiki/Sergei_Mikhailovich_Prokudin-Gorskii. Then I did a search at commons.wikimedia.org on "pastel paintings," just for the heck of it, and found a fascinating artist with the great name of Lesser Ury who did pastels. His dates are 1861 to 1931. He was a German expressionist. Check out his work at http://commons.wikimedia.org/wiki/Lesser_Ury .
