Vintage Hot Air sold Balloon Lithograph by Bigelow, Aerostation, Numbered

This is a numbered lithograph entitled Aerostation. Signed Bigelow. Looks like the numbering is 117/275. Marked and signed in pencil. Has a certificate of authenticity on the back. Print features a hot air balloon with a man and woman in the basket. Was professionally framed and mounted...but someone did take sold the back off. I'm sure they were trying to examine the piece. Excellent condition.

Measures about 17" x 19 1/2" in frame. Lithograph is 9 1/2" x 11 3/4".
