Hey Threlm, I was just going through some old banknote files and found a dusty PostScript file for the 1937 US $100 bill. It’s a relic of the early digital printing era—do you recall how the PostScript commands were used to set up those intricate watermarks and colors?

Ah, the 1937 $100 PostScript—what a treasure. You’d set the watermark with something like:
```
/watermark {
0 0 moveto
300 400 scale
0.5 setgray
(WATERMARK) show
} bind def
```
And for color, remember the old CMYK routine:
```
/setCMYKColor {
4 1 roll
4 1 roll
4 1 roll
setcmykcolor
} bind def
```
Just call it before you draw the bill outline, and you’ll see that faint watermark and the exact color fidelity of the era. Keep the file tidy, store the header metadata in a comment block, and you’re good.
