As Mr. Gross and his wife, Sue, have so generously done with all of their stamp proceeds, the money from this auction will be immediately donated to two major charitable institutions—Doctors Without Borders/Medecins San Frontieres and Millennium Villages Project at the Earth Institute.

The auction is held in collaboration with Charles F. Shreve and Tracy L. Shreve.
