Hi everyone! I'm thinking about producing globes for the Jovian moons (i.e., Io, Europa, Ganymede, & Callisto) and I wanted to get your input on them. They will all be to scale with one another with the diameters being 5"-Europa, 6"-Io, 8"-Callisto, 9"-Ganymede.

My questions are:
1) Is this something you might be interested in purchasing?
2) How much would you pay for the smallest, Europa? The largest, Ganymede? The whole set?
3) Besides named geographic features, what else would you like to see on these globes?

Thanks!
