what`s with the "GB" Logo - is it supposed to be included as well, or just to show how you wish your final work to look like?

It's my logo.I just offered its in case you thought it could add to a design.

Nice work everyone! At this point Jay design has submitted the most attractive design. Don't be discouraged by this… I am sharing this information so that you all have an idea of what I'm looking for. What I like about this submission is the top half of the globe including my mascot, the sun, the mountains, and the trees.

Easy Morente has done a good job with his design… Especially the lower half with his use of text wrapping around the baseball and his use of a baseball at the bottom part of the sphere

no one has an idea of what you're looking for because contest is blind:
