Since two of my main numismatic bibles, the Big Green Withers book and the Charlton catalog (not to mention dealers and auction houses) cross-reference to Courteau numbers where applicable, I've found it helpful to have my own Courteau on the shelf, so to speak.
If you want a Courteau at your fingertips, just follow these three quick steps.
1. Go to the
Newman Numismatic Portal here:

2. In the search slot, type in
Numismatist, May 1924.
3.
Et voila! Courteau's on pages 349-357.

When the viewer opens up, you can bookmark the link for future use on your "device," and/or you can download it in one of the half-dozen or so formats shown toward the bottom half on the screen. Print it too, if you'd like...it's in the public domain.
Enjoy!
