Hi,
I’m wondering if anyone can help me with something related to Dan. I had the pleasure of knowing Dan for 30+ years as my mother married him in 1982. In the process of cleaning out his files/records (along with his 2 sons), we have come across a number of vintage materials that I’m sure would have value to collectors or others interested in typography. Can anyone recommend how we could go about determining what is valuable/of interest and what is not? Please let me know via post, or the moderator has my email. Thanks.
Dave

I couldn't figure out how to contact the site's moderator to suggest Typophile or other sources to him.
