If you're talking Aparo in the 1970-1977 era, I think there's a chance an Aparo/Wrightson book could yield some nice results.
If you're talking Aparo in the 1983-1993 period, as demonstrated by the above examples, some of the best inkers in the business, I don't think any inker could have turned those pencils into gold.
