How Large Can I Print?
In general, at 300 DPI, you should at least be able to double the size of the actual image, more so with our 600 DPI images. So, if the original was 10 x 12 inches, you can print at 20 x 24 inches, without quality loss. If your display requirements can accommodate some loss in image quality, you can make it even larger. That being said, no quality of scan will allow you to blow up at 10 x 12 inch map to wall size without significant quality loss. For more information, it is best consult a printer or reprographics specialist.
Refunds
If the high resolution image you ordered is unavailable, we will fully refund your purchase. Otherwise, digital images scans are a service, not a tangible product, and cannot be returned or refunded once the download link is used.
Cartographer
Samuel Lewis (c. 1754 - 1822) was an American engraver, cartographer, draftsman, and geographer active in Philadelphia in the first of the 19th century. Though is place of birth is uncertain, most agree that Lewis emigrated from Dublin, Ireland, in the late 18th century. Lewis' earliest cartography work was produced in partnership with the well-known Philadelphia publishers Matthew Carey and Henry Schenk Tanner. In 1804, with the intention of republishing high quality English maps in the United States, Lewis partnered with the eminent British map publisher Arron Arrowsmith. Their first joint publication was A New and Elegant General Atlas, but many others followed including an American edition of Arrowsmith's important double hemisphere wall map of the world. Arrowsmith also worked with Jedidiah Morse, among other important American cartographers of the period. Ralph Brown considers Lewis to be "the most enterprising commercial map-maker of the period … " Lewis is best known for his map related to the expedition of Meriwether Lewis (no relation) and William Clark. In 1814 Lewis, copying directly from William Clark's manuscript, issued A Map of Lewis and Clark's Tracks across the Western Portion of North America. This important document was the first published map derived from the Lewis and Clark Expedition and profoundly transformed the cartography of the American northwest. Samuel Lewis of Philadelphia should not be confused with Samuel Lewis of London, another cartographer active during roughly the same period. More by this mapmaker...
