Bishop Graphics made layout tape and had "puppets" for ICs and Transistors.I think the same. The large copper pours indicate pen traces.
In the past PCBs were drawn with a specific type of adhesive tape (the name/brand escapes me now) that had very similar curved traces as shown in the picture (some of them are works of art), but the large copper pours were not as common.
Well, that or someone had fun with Autocad!
