Black bowler hat, or Derby if you are American. It has a grosgrain hatband, leather inner headband and red satin lining. Wool felt. Label says Christys' London, Made in England. 1960s-1970s.
Size - Small, 6 5/8
Very good condition. One small scuff on the top, see photo. Part of the lining has come unglued but it stays in place tucked in beneath the headband.
