This is page 4 of 5 of the Duncan Webb draft version, with sheets 18-28 of 28, full-scale at 1/25 M.

For explanation, full view (reduced to ca. 1/71 M), and octants 1-8 at 1/50 M, go to page 1.

For sheets 1-6 of 28, full-scale at 1/25 M, plus 5 full-size insets, and a photo of the assembled map, go to page 2.

For sheets 7-17 of 28, full-scale at 1/25 M, go to page 3.


For 10 selected images at 1/10 M, go to page 5.

As mentioned on p. 1 and 2, Duncan Webb's "World Political Map" is an incomplete draft, from which my own printer could not make a direct copy of the pdf; only inferior screenshot jpegs. Nonetheless, to preview his wall map in its full size, 84 cm x 164 cm (ca. 33" x 64"), I spliced together 28 of those dubious jpegs on letter-size paper (+ 4 extra sheets to reassemble Antarctica, Russian Far East, Iceland, etc.). A severe defect of this splice is that the jpeg-prints do not show the 1º meridians and parallels, while the 5º ones are barely visible.

#25 of 28. Note: make 2 of these, so you can cut out the Antarctica piece along 60º. (Beta-2 had Antarctica, etc., digitally
attached in one piece, but Duncan had not yet included that here.)
