Option #1 - Buy a Frame from Amazon.com and Frame It Yourself
To make framing easier, below are some links to Amazon.com products that will fit your Passport Map perfectly.
Option #2 - www.FrameItEasy.com
Purchase your Passport Map already framed from www.frameiteasy.com. With this option, I will email you a high resolution image of your final map. You then upload the image on the Frame It Easy website. From there, you can select any size, color and matting that you prefer. Their quality and professionalism is excellent.
Option #3 - Bring Your Map to a Frame Shop or a Craft Store
After you receive your printed map from me, bring the map to a frame shop or a craft store like Michael's, AC Moore or Hobby Lobby. They should have some options for you. Remember, the opening size should be 12" x 18". The maps are printed on 13" x 19" paper and I leave a 1/2 inch around the margins in order to allow the map to attach to the mat.
