A Retro 51 rollerball pen brimming with Hummingbirds and Flowers. Sculptor and artist Dr. Shirley Bauker’s famed Woodland art designs grace this unique Retro 51 Tornado rollerball pen, produced in collaboration with the Smithsonian Institution. Dr. Bauker’s exquisitely detailed Woodland Hummingbirds and Flowers carvings are acid-etched onto the barrel and then plated in stonewashed copper with accents to match, achieving the dramatic effect. Each pen is individually numbered in this limited edition and packaged in a commemorative tube that can be used as pen stand.
