Would anyone know the mailing addresses respectfully for Mathers & Dow; or know where I can find them?

Thank you for your response.

No, but here's Mathers' site, which might have a way to contact:

Tony Dow appears to have a site on Facebook.

I don't see an address on his site but that all night flea market in Illinois woudl have been fun. Too bad I live in Washington.
