I have somehow arrived

The package in today's snail mail has me beaming. Mainly I'm grinning at the notion that I have somehow Arrived. Because who *else* is in the SF Historical Trading Cards collection? Jules Verne, H. G. Wells, Isaac Asimov, and Robert Heinlein, to name a few.

As a bonus, it tickles me to have joined such august company bearing number 360. (Yes, cards of the aforementioned have much lower numbers. But still.) Maybe it's from some association with 360 degrees in a circle. Or an ancient Babylonian gene expressing itself. 

Theories welcome.
