Variant 2 of previous 'Hub-Wheel' design. This is the Day-Night variant with more details to punch up the fun. There is the sun and moon, clouds, a biplane (partly representing aerial remote sensing and that Boston was an early contributor to aviation), a kite (Boston was also the site for early weather observations of the atmosphere using kites), the International Space Station (there are Boston connections there, too), and a superhero patrolling or perhaps looking for the child floating in the air while holding onto balloons. I'm sure things can be substituted. I wasn't sure how much to put in so I stopped here before it got too crowded. - Same as png - this is in pdf.
