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 S
Reading Howell (1743 - 1827) was a Pennsylvania based engineer, landowner, and surveyor active in the late 18th and early 19th century. While little is known of his personal life, records do survive of his surveying projects, including detailed surveys of the Delaware, Lehigh, and Schuylkill Rivers. In 1789 he was commissioned by the assembly of Pennsylvania to, for the sum of two hundred pounds, to produce a detailed map of the state. This map, which was initially published in 1792, was the first map of Pennsylvania to be issued following the American Revolutionary War. This important document would prove to be the finest and most important map of Pennsylvania to be issued to date, incorporating, as it did, the wealth of cartographic information generated by both American and British military surveyors during the Revolution. From 1804 to his death in 1827, Howell held the title of "Principal City Surveyor" as well as "City Regulator" of Philadelphia, where his name is attached to numerous surveys related to land disputes.

John Vallance (1770 - June 14, 1823) was a Philadelphia based engraver active in the late 18th and early 19th centuries. Vallance was born in Glasgow, Scotland. Some scholars claim he apprenticed under Philadelphia engraver James Trenchard, but the dates don't work, as Vallance moved to the United States at 21, already an master engraver. At 21, in the year 1791, Vallance moved to Philadelphia and immediately partnered with James Thacakara, his wife's (a Trenchard?) uncle, establishing the imprint of Thackara and Vallance. The firm completed numerous significant cartographic projects, including maps for Andrew Ellicott, John Melish, Henry S. Tanner, and Reading Howell. Vallance later partnered with Henry Schenck Tanner (1786 - May 18, 1858) and Francis Kearney, forming Vallance, Kearney and Co. Vallance, working with Thackara, produced some of the most important early maps of Washington D.C., engraved early Continental Currencies, and worked on Dobson's Encyclopedia. In addition to his cartographic work, Vallance was also one of the founding members of the Philadelphia based Association of Artists in America. Learn More...
