I believe Bill Schwab's...
...a humble man who's secure in himself as an artist.
How do I know this, apart from his concuct here on APUG? His website has the most links to other photographers websites represented by major galleries who sell on the web I've ever seen (from a photographer represented by those or other major galleries);
That takes knowing who you are as an artist. That takes class. That takes guts. That prompted me to post this.
P.S. Sorry Bill :( I just re-read this puppy and it does come across as way too saccarine sweet! Cudo's to you for sharing your links.
