I haven't stated it explicitly here yet, but "north" locations default to all white if no tile and "south" locations default to all black if no tile.

Fixed the northern extent and flipped the polarity below "sea-level":

David Glick has pointed out there's a `13n1e` which goes against my earlier comment about `8n` being the "north"-most extent. Recalculating some pictures now...

Here's a 1/64th scale version (which this site will further scale to fit the card):

Here is a (hopefully bug-free) version of where the tiles are:

Hmm, looks like a bug is causing the symmetry, not the data.

With the extra 13 tiles, that means the pixel count is actually 943,718,400 (although that's just the locations for which there are tiles; arguably there are "pixels" in the white areas above too)

I'm suspicious I haven't got it right yet, though, as there's nothing in the lower half.

There are, however, 212 actual tile locations that don't `404`. That's still 889,192,448 pixels!

The full extent seems to be `8n` and `19s` in the vertical and `33w` and `48e` in the horizontal.
That means an 81 x 27 tile extent (or 2,187 possible tile locations).

I wrote a quick Python script that starts at `1n1e` and successfully attempts to load in each of four directions (keeping track of where it's already been) to explore the entire contiguous tile set.

XKCD's [Click and Drag](http://xkcd.com/1110/) is a wonderfully massive drawing with all sorts of hidden gems in it if you're willing to, well, click and drag.
