PatentWear’s Museum Series designs are available in both color and line art versions as shown. The “lineart” version—as drawn on the original patents—is printed in a single color, usually blueprint blue unless otherwise indicated. The color versions are digitally hand-painted in an artistic interpretation of the patents’ realistic results. This series differs from other PatentWear designs in that they are all created from multiple significant patents for each subject (instead of a single-patent focus). Actual patent numbers, filing dates, and inventors are included in artistically arranged compositions depicting the subject’s evolution on which today’s version is most definitely dependent.
