The sizes listed for each chart is our "Gallery Standard" size. The charts can be printed in nearly any dimension up to 44" wide by whatever length is proportional. A Stretched Canvas is limited to 40" by any length because a border is needed for stretching. Paper prints, and Canvas prints with Grommets, can be 44" by any proportionate length. Each of these are less expensive than a stretched canvas because of labor. If you would like a print on paper or canvas with grommets call or email the gallery for pricing. Please keep in mind that ANY SECTION of the Thousand Islands can be printed almost any size to meet your needs. For example, if you wanted just the TI Bridge to Goose Bay it can be printed, up to any of the sizes listed, (44" - to the proportionate length it comes out to) Additionally: GPS Markings can be added, stars to highlight special places, any text you would like, personal photographs, & even a Michael Ringer painting. Each additional customization is $10 per item.
