Notes:
This map was originally printed in two sizes: approximately 11x17, and full poster size. This scan was made from the smaller of the two.
The creases in the image (see sample, below) existed in the original poster I used; apparently the original 1968 map used to reproduce the more recent poster had been folded in eight segments.
These files are large because, to preserve clarity of the font, I had to use high resolution and high image quality.
If you open these images in a browser, the lower-resolution images will appear smaller than the higher-resolution ones, even though their actual width when printed will be identical. This is because a browser, unlike a graphical application or a printer, will display each pixel of the file on one pixel of the screen, hence making it appear larger.
