Now graphic designers and sign builders are busy working on more than 600 individual projects that will reflect the new name.
The main marquee sign at the corner of Ontario and Carnegie will be 35 by 50 feet and weigh 6 1/2 tons.
Cleveland's Brilliant Sign Company will begin construction of the sign next week.
Contemporary Design Group is working on new designs for hundreds of printed items that will carry the new Progressive Field logo.
The graphic designers are working long hours, but most are Indians fans.
"It's cool to tell people what I do and see my stuff around the park when I'm there," said graphic designer Eric Buckmueller.
The staff at Contemporary Design Group knew about the name change to Progressive Field months before it was announced to the public.
How do they keep such a secret?
"First of all we have a very good group, but when somebody comes to work for us, especially designers, they all have to sign confidentiality agreements," said Renee DeLuca Dolan, head of the design studio.
While the main signs are expected to be in place by opening day, other signs reflecting the new name will be added to the ball park in the first half of the season leading to the All-Star break.
