John H. De Wild

John H. De Wild is a sparsely documented author whose known work centers on commercial lettering and display design. Library records identify him as the author of How to Write Show Cards and Elements of Show Card Writing, practical manuals published in the early 1920s for readers learning advertising card lettering and related retail display techniques.

The books themselves point to a straightforward, instructional approach. Records for How to Write Show Cards describe it as containing simple brush and pen alphabets, easy-to-follow guidance, and added material on retail advertising and window trimming. That suggests he wrote for shopkeepers, sign writers, and beginners who needed useful results quickly.

Very little reliable biographical information about his life appears to be readily available in major public sources, so his reputation today rests mainly on these surviving trade manuals. Even so, they offer a small but vivid glimpse of an era when hand-lettered show cards were an important part of everyday commerce.
