security note
I do not use instagram very often, but I have one old valid Insta account (davidw. mueller), and sometimes forward my FB posts about art there too.  it is valid, but others are fraudulent.  I do not have any blog accounts!, or other Instagram accounts. there are some fakes there too.
for safe CONTACT
I CAN SAFELY be reached via the contacts page and emails ON THIS SITE.  thank you!
