I don't have books to sell, but I'm happy to sign your copy if you follow a procedure that makes it simple for me to do so. First, send an email that lets me know the book is coming.
Send it to: mark(dot)bittner(at)earthlink(dot)net.
Then mail the book along with a self-addressed stamped envelope to:
c/o Pelican Media
1736 Stockton Street Suite 2
San Francisco, CA 94133
Sometimes people forget to enclose an envelope. Or they forget to put stamps on the envelope. Or they forget to put an address on the envelope. That makes things more difficult for me.
If you want a particular inscription, let me know. Otherwise I'll just sign it—usually on the title page below my printed name.
