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.
George Eldridge (November 27, 1821 - August 23, 1900) and his son George Washington Eldridge (1845 - 1914) were American makers of nautical charts and Pilot Books active in the late 19th century. George Eldridge was a Cape Cod fisherman known locally as an excellent ship's pilot. While recuperating from an injury in 1851, Eldridge drew his first nautical chart. The chart proved popular, and its success led Eldridge to pursue a career in hydrography - the science of mapping the sea with a special focus on navigation. Eldridge produced numerous subsequent maps and is credited with issuing some of the earliest accurate nautical charts of the American Atlantic coast. In time George Eldridge passed his thriving business on to his son, George Washington Eldridge, who continued to produce beautiful and practical maritime charts until 1924.Though most of Eldridge's charts were loosely based on U.S. Coast Survey work, they proved popular with navigators. The Eldridges possessed a talent, shared by both father and son, for distilling the often convoluted Coast Survey maps into practical nautical charts for the working mariner. From 1875, in addition to large format independently issued nautical charts, Eldridge also issued annual editions of Eldridge's Tide and Pilot Book and The Book of Harbor Charts. The Eldridge offices were located at 103 State St. Boston, Massachusetts. After the deaths of George and George Washington Eldridge, the firm passed into the hands of the latter's widow Sydna, and son-in-law, Wilfrid O. Wight. Wight's son and subsequent generations have continued to publish the Eldridge Tide and Pilot Book down to the present. More by this mapmaker...
Samuel Thaxter and Son (fl. 1792 - 1916). Samuel Thaxter (1769 - 1842) is the founder of a Boston dynasty of manufacturers of mathematical instruments and nautical charts. He founded the firm in 1792 and is first referenced in the 1796 Boston Directory. Around 1822 he incorporated his son, Joseph H. Thaxter (1801 - 1835), into the business renaming it 'Samuel Thaxter and Son'. The firm would retain this name for the remainder of its existence. This successful business was subsequently passed to Joseph H. Thaxter's son, Samuel Thaxter Cushing (1821 - 1882), in 1843. It was Thaxter Cushing who developed the firm's publishing arm, partnering with the Boston nautical chart maker George Eldridge. They are best known for 13 large format blueback charts focusing on the east cost of the United States published in the second half of the 19th century. They also published numerous smaller maps and pilot books. After Thaxter Cushing died the firm was taken over by his widow, Abby C. Cushing, who managed it until 1905. It was subsequently managed by Herbert Risteen Starratt and continued to be registered in the Boston Directory until about 1916. Learn More...
