Featured Pastel chalk drawing- horse

Probably a horse at the Annandale wine estate in Stellenbosch.
"These horses are a remnant of the days when it was also a riding school throughout most of the 20th century. The estate took something of a break from wine production during this time that had otherwise been ongoing for a continuous 315 years."
