With the rainy weather preventing me from observing the real Mars, I spent yesterday evening assembling this neat Mars globe. It's natively A4 and makes a 15 cm globe, but I had the PDF printed out on A3 at Officeworks which ends up making a 21.5 cm globe.
I'm actually finding it quite useful to identify some of the features on mars images I've taken so far this season.
It's just one of the one of the many globes downloadable from:

Enjoy!
