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.
Croydon Augustine Dockham (July 4, 1835 - September 6, 1907) was an American printer and publisher. Born in Methuen, Massachusetts, Dockham attended school in Newburyport, Massachusetts. He began publishing directories of Haverhill, Lawrence, and Newburyport, Massachusetts at the age of seventeen. In 1901 Dockham held the distinction of being the oldest living directory publisher in the United States. He established the Lawrence Daily Journal in Lawrence, Massachusetts, in December 1860 and operated the newspaper through the entire American Civil War. In 1866, Dockham began publishing his 'American Report and Directory of the Textile Manufactures and Dry Goods Trade' which dealt with 'the cotton, woollen, silk, and linen manufactures in the United States, Canada, and Mexico'. Dockham moved to Chelsea in 1877 while maintaining a summer home in North Reading. He married Margaret Anson in 1868, with whom he had five children. Dockham died of intestinal cancer on September 6, 1907. More by this mapmaker...
