Thanks guys for the positive comments. And I agree this is a great thread and really enjoy seeing it all.
Carlton you are correct about porcelain sports signs being rare. I should have previously mentioned it in case it wasn't seen by others when you originally posted
http://sportsantiques.com/spalding_bb_flange.htm about the porcelain Spalding baseball sign I picked up. If I'm not mistaken it's the only porcelain baseball related sign that I am aware of. Gas and oil signs, of which I also collect, were more commonly made of porcelain to withstand outdoor elements.
The Old Gold Sign here is new old stock as the cardboard stand up on the back is still flat on the reverse.
