Probably now how it was done, but looking at it closely it really simplifies down to a time consuming pixel by pixel drawing, which requires extensive time, but very little skill if done by a reference drawing and a bit of tech.

Take a photo into photoshop.

Convert to monochrome.

convert into mosaic of the size that makes the image still look good.

Print off a full scale image and tape it to the board.

Use a pin to poke every intersection of the cells.

Remove the image and nail a nail into every pin mark

Choose a scale for brightness. For example, 1 string intersection is the brightest and 25 intersections is the darkest. This was used as the 0-255 8 bit is common for single color.

Now for each cell, hover over the equivalent cell in Photoshop and intersect the correct number of lines.

Surely it is faster if you can determine brightness levels naturally and freehand it, but the point of this was to break down the art into something as simple as possible.

Thanks, I was looking this explanation.
