Where better to find a nice-looking letter that a book about Gutenberg himself? This open letter A image dates back to at least 1860 when it was included in a biography about the famous printmaker. I wish the letter was both larger and a bit less pixelated but I’ve shared it with everyone because it could easily be colorized.
Hope you can find a great new use for it!
