Coast survey chart: Potamac River (in four sheets).

WHAT YOU GET — 5 JPEGs at 300 DPI

• 8x10 in (2.5 MB)
• 11x14 in (4.7 MB)
• 16x20 in (8.1 MB)
• 18x24 in (10.2 MB)
• 24x36 in (15.3 MB)

8x10, 11x14 are true 300 DPI from the original scan. 16x20, 18x24, 24x36 are enlarged to reach that size, which holds up framed but is not native resolution. I would rather tell you that than let you find out.

WHAT I ACTUALLY DID TO IT

The library scan arrived with the scanner surround still on it and a century of grey in the paper. I trimmed the surround, stretched the tone back to warm paper, and took one pixel of scanner speckle off — the soundings stay sharp, the age stays in. Sold as wall art, not for navigation.

HONEST ABOUT THE SOURCE

The original scan is a public-domain record from the Library of Congress Geography & Map Division (a U.S. Coast Survey era chart, published before 1930). You could download it yourself for nothing. What you are paying for is the restoration and the sized, print-ready files — not access to the chart.

HOW TO PRINT IT

Any print shop, any online printer, or at home. Ask for matte or a cotton rag if they offer it. The files are RGB at 300 DPI with the density tagged, so a shop will size them correctly without asking.

NOT INCLUDED
