DENVER — The next time you take a drive through beautiful downtown Denver, don't forget to look up — you never know what you might see. 

Those who look up in downtown Denver right now might catch a glimpse of an elaborate Post-it Note war going on between multiple companies in a host of office buildings. 

The photos are collecting under the hashtag #5280postitwar on Twitter and Instagram, and they're incredible. 

According to one worker inside the former CenturyLink, now TransAmerica, building at 1801 California, the war started with simple notes before blossoming into full-blown works of art.

"It was a week-long Post-it Note war," Ryan Besch, a copywriter, said. "I can't nail down patient zero for who put what up first, but it started with a simple 'hi' or 'hello' on one side or the other." 

Besch's office took it a step further, putting up a small Pac-Man ghost made from orange Post-it Notes. 

"I came back Wednesday morning ... we were shocked. We came back and there were a ton of things," Besch said. 

Thus far, works of art have included Pac-Man characters, Mario characters, Star Wars characters, Simpsons characters and more.

"Other businesses we never interact with are engaging in this," Besch said. "It's impossible to get that level of coordination over two or three stories. It's gotten to a point that it's crazy." 

Besch said the current battle is ongoing on about the 18th or 19th floors of the building, but growing popularity around the hashtag suggests other office buildings may be participating, too.

"We're all just doing our own thing and that's what makes it awesome," Besch said.

Unfortunately for the Post-it Note artists, it appears the building manager is not in support of the creative and ongoing war. 

The building management team in charge of 1801 California says the tenants are now in violation of their leases. It demanded the tenants take down the artwork by 5 p.m. Check out the email below.
