1/6 ambrotype on colored glass, behind mat and cover glass in full thermoplastic case. Overall the image and case are in very good antique condition. The case has some minor chips and a very well-done repair on one of the hinges, otherwise it's very nice.. clicks and stays closed. 

Shipping: Well-packed First Class mailer or boxed Priority Mail.
