Postal Stationary Lithograph

I'm looking for some tutoring. I have some postal stationary I'm identifying. The attached is for UZ3. I think it's a run of the mill card; however, when looking at a Scott Specialized catalog I notice the Litho. pricing. I'm quite sure this isn't a Lithograph but can some one comment and provide an example of a lithograph? I don't find any information in the catalog -- but haven't read it cover to cover. Thanks.

My Scott Specialized (2018) doesn't mention litho nor does my United States Postal Card Catalog (2015). The UPCC does tell me that this card was printed on the web-fed Potter-Hoe rotary press by letterpress as was UZ2. Can you post a scan of the catalog section in question?
