I wrote about Tepper here and also mentioned him in other posts: use the search item on the right side to find them.
One way to classify illustrations has to do with whether or not they completely fill a square or rectangular framed space. Those that do not are call "vignettes." They include the subject people or objects often with a bit of environmental detailing. But there is much blank "white space" that sometimes would be filed with text when published.
Tepper made a number of vignette style illustrations. Some can be found in the link above. Others are presented below.
