Boy.... #31 is the comeback kid! It is getting a lot of attention when we show the logos around. Can you try changing all the black to white, and then the lettering to either black or the dark green. DON'T take the grey off the top like you did in the other ones.
Also, can you give us #31, just like it is against a white background... or our green, so we can see how it may look on shirts and signage.
Thanks so much.
