National Park Service
This is a collection of event posters used for publicity around events as well as used for graphics on the park's website (http://www.nps.gov/gosp) and mobile app. This series began as a commemoration of our summer events and has branched out to include earlier events and will likely continue throughout the upcoming years.
Now, there is a secondary series of posters for marketing use throughout the year. These will remain undated and though some may be tied to specific events, they are easy to repurpose for site banners where the CMS system can be customised for the addition of dates, times, and other pertinent info, should it be deemed necessary.
