Finding All Scott Numbers For A Single Illustration

I'm having a bit of trouble finding all the Scott numbers for a single illustration. Most of the time there is only a single number. And, for U.S. Definitives, there is the Identifier section just prior to the listings (in the Scott Specialized U.S. Stamp Catalog). It lists all the numbers for a particular illustration together in one place.
For example, I was trying to look up a Winter Olympic Games issue from 1932. It is illustration A222. Immediately below the illustration is number 716, Skier. However, the catalog also states "Flat Plate Printing". I looked around but can't find any other numbers. Was there a rotary press printing? If so, where is it? If not, why is the notation made? Is there any cross reference in the catalog that I may be missing? Or maybe some other publication? Or maybe I/we just need to scan the catalog. Any suggestions from the experienced would be appreciated. Thanks!

The Scott catalog gives a printing method for all stamps, whether there is just one method or more. Does this answer your question?

If there had been a rotary press printing it would have been listed right underneath. Just as the Harding stamps are listed (610-613).

Thanks, that helps. I probably should have asked if commemorative can have different numbers spread out like definitives, such as definitive illustration A140. It has numbers from #405 up to #546, with other stamps/illustrations within that range.

Yes, commemoratives can have their catalogue numbers spread out. But it doesn't occur all that often, in part because, unlike definitives, commemorative issues tend to have a relatively short life span, usually at most a couple of years. Definitive series, on the other hand, can continue for many years. In addition, commemorative series have well defined sizes (in number of different designs) at the outset, whereas the number of designs in a definitive series is almost always unknown until the series has almost run its course. For these reasons, the gaps between catalogue numbers for similar commemoratives are much shorter than for definitives. The first commemorative issue with such a "gap" that comes to mind is the National Park series of the 30s. Other "gaps" have been created in more recent years by rate changes, where the same designs are issued with two different denominations. Examples include the 2005-06 Reagan (Scott 3897 & 4078) and the 2002 Greetings from America (Scott 3561-3610 & 3696-3745).

Many thanks, JLLebbert, and the others, too, of course!
