Homebrew PCBs

Many of the old PCBs were made with phenolic PCB material.  The color 
varies between brown to various shades of beige.

You can still purchase bare (blank) copper-clad phenolic PCB material.

Another characteristic of old PCBs is that the layout is often done 
by hand, using crepe dots and crepe tape in various widths.  Even 
earlier layouts were strictly hand-drawn - no tape or dots.
