Francine,
We purchased a couple of the "Munsell Soil Color Charts" handbooks in
1990. The address then was:
Munsell Color
Macbeth Division of Kollmorgen Instruments Corp.
2441 N. Calvert Street
Baltimore, MD 21218 USA
tel: (301) 243-2171
fax: (301) 243-0028
tlx: 87540
The "Soil Color Charts" (1990 ed.) is a subset of 7 charts from the
complete Munsell Color System. We also purchased the complete set for
over $600 US, as I recall.
