DENVER -- The mayor of Denver wants your help in selecting the first "Denver -- Mile High City" logo, used for marketing purposes and not to replace the city seal.

He is asking the public to vote on the best logo from three finalists, after collecting feedback from more than 300 regional marketing professionals and city staff members.

Mayor John Hickenlooper said the logo is the next step in building a stronger identity for the region.

Viewers can e-mail their vote to milehighmarketing@ci.denver.co.us or fax in a selection to (720) 913-1802.

The deadline to submit the selection is April 12. Make sure to indicate logo A, B or C.

Logo A reinforces the fact that Denver was recently voted the most livable city in America, the mayor's office said. A historic building and a high rise border a park against the mountain backdrop, communicating the fact that Denver has more parks than any other city in the United States. A lower case "d" is formed by the arrangement of the images.

In Logo B the inverted "v"s become arrows that point upward suggesting growth, altitude, or the mountains. The overriding message is that people look at things in a different way in Denver. We are a vibrant city that is moving up to the next level.

The capital "D" in Logo C is a graphic rendering of a city building that could be an office building, a hotel, or any high-rise that sits in front of the Rocky Mountain backdrop. The sun emerging from behind the building denotes the fact that the sun shines on the Mile High region 300 days a year.

The Mayor's Office said no tax dollars were spent developing the Denver-Mile High logo. When voting, viewers are asked to keep in mind what the logo would represent.

"Denver is an energizing place to be where people get more out of every day. Whether in business, recreation or culture, active people and families thrive in the Mile High City," the mayor's office said. "Based on the positioning research, the core attributes of the region are: energizing, thriving, smart, Mountain West, entrepreneurial, adventurous, dedicated, can-do and new."

Although the logos are currently shown in black and white, color will be added once a final design is selected. The public is also asked to recommend colors for the logo.

Hickenlooper will unveil the official logo the week of April 19.

The idea of creating a Mile High logo came out of the recent Denver 360: Mayor's Marketing Summit -- a collaborative gathering of more than 150 marketing, branding, public relations and advertising experts from throughout the Denver metro area. The group met in February to discuss ideas for developing a unified Mile High Marketing Initiative for the region. The logo will be used as part of this initiative, as well as to better identify all programs within the city.
