If you're on the fence regarding who to root for in the 2014 World Series, it's worth noting that stationery nerdery is in the Kansas City Royals' DNA.
Todd Radom, the go-to guy for all things sports branding, has a great post up about how 15 artists from Kansas City-based Hallmark competed to create the Royals' logo:
The winning artist was Shannon Manning—a White Sox fan at the time. A package designer at Hallmark, Manning’s now-familiar crown logo embraced the dominant corporate branding style of the late ’60s—a relatively simple visual featuring minimal typography, enclosed within a bold, graphic geometric shape. Contemporary and striking (especially in the context of the world of sports identity at the time,) Manning’s work holds up remarkably well today.
I would have gone with the psychedelic cow logo personally, but that's just me.
