Lincoln as a 42x56 GIF (2 colors):
The picture I worked from, FYI.
Assuming we cut 6x8 tiles from sheets of paper/whatever, 42x56 works out to laying out 7x7=49 sheets of tiles. 6 of them are solid white. None are solid black. I consider 6/49 to be a happy accident, since solid is "boring". This didn't even occur to me until I started breaking it up.
Here are the plans for those 49 sheets, reading left to right, top to bottom. If you can resize your browser window to allow 7 images across, you'll see Lincoln here.
Run-length encodings for the individual 6x8 tiles.
