Guarantee & Returns: We strive to use the highest quality materials without cutting corners to reproduce this unique art. Since the discovery of some original posters in the past 10 years, we have made small design updates and even color changes that we feel make these posters closer to the original designs. Remember, each poster is individually hand made and therefore slightly different; this is especially true of our split fountain posters (Hawaii, See America Arches, Petrified Forest, and Mt. McKinley) If you are not 100% satisfied with our products, return them for a complete replacement or refund.
