National Society of Mural Painters
Originally known as The Mural Painters, the National Society of Mural Painters (NSMP) was founded in 1895 by a group of artists, dedicated to working together to represent the interests of mural painters in major public issues. NSMP collaborated with the Fine Arts Section of the Treasury Department, The Arts Project of the WPA, and the design boards of several World's Fairs. As a member of Artists for Victory, NSMP was allied with activities connected with World War II; many triptych altarpieces were painted for use by the armed forces through the Citizens Committee for the Army and Navy, Inc., and barracks and camps were decorated as well. The current membership is a diverse group of national and international artists qualified by application and acceptance. Society members work with other organizations, actively sponsoring legislation and allocation of funds for the development and commission of public works of art.
I've been using Koh-I-Noor Rapidograph Technical Pens since 1969. My aunt bought me my first set when I was 12 and I have used them daily ever since. I love the fact that I can mix my ink colors to match my watercolor or my wardrobe and use "Pelikan Drawing Ink A" almost exclusively. Though the inks made by Koh-I-Noor and Winsor Newton are satisfactory.
If you are a beginner, I would NOT recommend purchasing anything smaller than an 0 (0.35 mm). Even as a professional I find cleaning a 4x0 to be a challenge. I work most often with a 2x0, and find them to produce the smoothest flow, if kept clean.
I use this tape to hold the Mylar on the drafting table. It's a very good tape! It releases without leaving residue, and it is thin enough to let the rule slide on top. The tape doesn't break while unrolling, unlike many others.
I highly recommend it.
