Very nice. Figure 6 is a classic French touring bike. Check out how the RD is mounted (that looks like it might be a constructeur bike) and the shifter for the FD mounted on the seat tube (at least that's what I think that is). Plus I love the pic of the PX 10 set up as a "touring" bike. The article was pretty clear that in the 70s, most Americans toured by repurposing a racing bike which was not that crazy in the 70s since those bikes often had clearance for decent volume tires and eyelets. The gearing was a whole different story though.
