I have not done any serious PCB work for years but back in the early 70's I made lots of one off PCB's all hand drawn with a texture colour pen.
If we wanted duplicates we did them with silkscreens. Most of it was discrete components. However I designed and built an eight digit frequency counter with nixie tubes and TTL which was the latest technology. All laid out and drawn with a pen.
I have attached a couple of scans from my archives of some sections of a VSB colour TV transmitter I built using hand drawn boards. The technique was to lay the circuit out on graph paper then transfer the design to a PCB board by marking all the holes on the board with a scriber then drawing the board again on the copper side then etching in ferric chloride which we used to buy in bulk. Terrible stuff to handle.
