Poster information: This print is created in a style similar to the traditional WPA (Works Progress Administration) National Park posters of the early 20th century. We apply an effect that mimics a watercolor painting during our creation process. Print information: We use 100#, coated fine-archival paper for our posters. The paper is 100% acid-free with a beautiful matte finish and ready to be framed. Our postcards are printed on heavy cardstock. Processing and shipping: All posters are usually shipped within 1 week of ordering. Quicker processing is available if needed. We seal each poster with care in a rigid tube or envelope to prevent damage. Free shipping in the U.S. 100% Guarantee: In the event that your poster arrives damaged or is not to your satisfaction in any way, we will make it right or refund your money 100%.
