A specially designed philatelic souvenir envelope has been prepared for the 58th Pittsburgh Conference and Exposition on Analytical Chemistry and Applied Spectroscopy. This is the 31st in a series honoring a famous scientist or an event in
science.

The cachet and insert honors Dr. Jonas Salk, a pioneer in medical research. The cacheted envelope will be available at the Philatelic Booth during Pittcon 2007. Interested collectors who are unable to attend Pittcon 2007 may obtain one to three envelopes at no charge by sending a request, together with a self-addressed stamped no. 10 envelope (SASE) to: Philatelic Cachet, c/o The Pittsburgh Conference, 300 Penn Center Boulevard, Suite 332, Pittsburgh, PA 15235-5503. If a cacheted envelope which is stamped and hand-cancelled during Conference Week is desired, please enclose current U.S. first class postage for each envelope requested.

The Pittcon 2007 Philatelic Booth will be located in the Level 1 Lobby of McCormick Place South. At the Philatelic Booth, cacheted envelopes with a variety of older science-related stamps will be available for $2.00 each. These also can be
ordered by mail with an accompanying SASE.

A U.S. Postal Service substation will be located adjacent to the Philatelic Booth where postage stamps can be purchased and letters and cards can be hand-cancelled.
