On the iMac-era silly little KB, it is pretty italicized, on the Apple KB that came with the Mac Classic it is slightly less so.
The KB that I use is a Kinesis Ergonomic one, not Apple branded, and the symbol is not italicized. It's also written in a heavier line on the Kinesis than on either of the other two, and tighter together.
I can't figure out how to type it. opt-shift-k is an apple, but I never could find the command key.
Much luck with the tattoo! Any thoughts of adding the rest of the keyboard?
