Bas-relief of General McClelland Copper -

I purchased this today at the thrift shop thinking it was just a cowboy on a horse. I was taking photos and when I looked closer I realized it was a soldier. I found the same one in my local MFA collection. https://www.mfa.org/collections/object/bas-relief-of-general-mcclelland-39397?fbclid=IwAR1wxyzzYCfvDcnUqszfg4l2pUKoDv7YBtJzOutVcGMUhGEVwGTK7R31DiU
