HI,
Is there a size requirement for this poster?

Nope - just thinking normal 11x17 size but I'd be open to options.

what are other text contents you need to be include in the poster besides the date?

Celebrating 175 years of Chattanooga

Week-long celebration of community-sourced events.

This is too wordy but here's from the ABOUT portion of the website - might provide some inspiration:

CHA175 is a week-long event designed to showcase the unique history and culture of Chattanooga. By community sourcing events, CHA175 will be a celebration for ALL our citizens.

Whether you were born and raised in Chattanooga or a recent transplant, this is your week to celebrate our City and learn more about our community. So pick a subject that interests you or a neighborhood you have always wanted to visit. CHA175 is the time to get to know our city, all of it - our neighborhoods, our history, our organizations, our future and each other, the wonderful people we call Chattanoogans.

any updates!!!
