We assume that they belong to the Art Nouveau style because they were found in an Art Nouveau pattern collection on the Internet. This collection mostly included various decorative patterns from books and magazines, illustrations by famous Art Nouveau artists, and the like, so we assume that the above designs have a similar past. Also, designs of various shapes, and even frieze or repeating patterns can be drawn in a similar way.
In our category SHOWROOM you can see how Mr. Brad Gothard used two designs to decorate pens. We hope that these Art Nouveau designs you can use to decorate the items you produce.
