I found this one not from from Schenectady, NY, where the H. Mischler who drew it seems to have had a business "furnishing plans and giving estimates"--though I can't imagine his plan here for a rubber band powered "Automoble" [sic] was an especially lucrative job! I really love it as a stand alone drawing and plan though, with this very chipper looking vehicle rendered in profile and from below, and then wonderfully dense grid below carefully charting the dimensions of seatbelts and windshields and engine!
10 1/4" x 8 3/4", graphite on thin, watermarked paper. Good condition, with a small loss to upper left corner as evident. Not brittle.
