DENVER (AP) — Denver Mayor Michael Hancock is kicking off a weeklong celebration leading up to the Broncos’ Super Bowl game against the Seahawks.

Hancock will join Gov. John Hickenlooper at a rally from noon to 2 p.m. Sunday at Denver’s City and County Building. The festivities will include a chalk artist who will create a tribute to the team along a nearby street.

Beginning Monday, fans will be encouraged to post photos and videos on the mayor’s Facebook page, based on a different Broncos theme each day.

Several buildings across the city also will be lit in blue and orange before the Broncos play the Seahawks next Sunday.
