412 is the area code for Pittsburgh and is all over the place with branding and slogans. Area codes in general are a common signifier within communities and the population. It’s always neat to see locals rep their area codes as advertisement or branding, I like it
I was surprised moving from Atlanta to San Jose that they have very similar area codes (404 408).
I was extra surprised that there's a chain of crepe places called "Atlanta Crazy Crepes" which as far as I can tell are located only in Akihabara in Tokyo and Eastridge Mall in SJ.
April 4th is an informal city holiday, "404 day".
Lots of artists and companies make "404" branded stuff, and you generally see the number all over the city:
