This is one of eight original illustrations by an artist whose estate was dispersed last summer. The artist was art director for Popular Mechanics Magazine, as preserved on the label that was on the backs of each piece. The artist's flat files were full of a life-time of fine illustrations he had done for major corporations, magazines, private commissions, agencies associated with the space program, .and even museums. These gun illustrations were unframed, as would be expected. They are probably a combination of pen and ink and also airbrush. I do not know who the gun manufacturer is but gun collectors will probably know. The dimensions of this framed piece are 17" long x 9.75" high. The Image size is 10.25" long and 3 3/8" high. The artist name is Thomas Dauer.
