Prints are of lab quality and produced with a Canon dye-sublimation printer. Each print is coated in a protective covering as part of the printing process, and Canon says it will last 100 years.
They are available in a size of 6 x 4 inches. Please note that due to the nature of printers, an ordered print may have slightly different cropping to the illustration.
To retain as much of a scene as possible, occasional prints are in a letterbox format. The quality of an image relies heavily on my source postcard, some being very hard to obtain.
