Bohemian glass jug

Bohemian clear glass jug of faceted baluster form with small loop handle and with white enamel decoration depicting a young boy in his Sunday-best knickerbockers, chasing a butterfly, in a landscape of ferns.
This type of work originated with Mary Gregory, who was American and worked for The Boston Sandwich Glass Company.
