During the early '20s to late '40s, books on showcard writing and hand lettering were fairly common. Unfortunately, the demand for hand lettering has lessened and finding good basic tutorials is difficult.
The images in this section are from a 1942 book by C.R. Havighorst called Simplified Show Card Writing.
The Basic Gothic Alphabet: Using strokes showing in Part 1, this set of letters can be easily achieved.
Numbers and punctuation are also created using the same set of basic strokes. Practice, practice, practice!
In laying out a show card, first rule the guide lines as shown. Then rough in your copy lightly with a soft pencil or charcoal stick. If the spacing is not exactly right you can easily adjust this when you do the actual lettering, as shown in the third line of copy above.
