A lot of sixteen original antique boxes containing one dose each of American Horse Tonic put out by the Dairy Association Company Lyndonville Vermont along with their original master box. Each one of the single unopened dose boxes measures approximately 2 3/8" long by 1 1/4" wide and all are in excellent condition. The master box has some wear, loss and soil as shown. A great item for the collector of Antique Veterinary Medicine related items.
