I have been collecting proofs for more than thirty years and am always happy to discuss proofs or answer questions about them.

Feel free to e-mail me if you have questions, if there are proofs you want to trade or sell, or of if you want to provide information to help complete the catalogs on this site. Any suggestions for improving the website are also welcome.

You can reach me at "info" (without the quotation marks) followed by the @ symbol and the website address, "".
