Victorian Advertising Card Ayer's Lactart Milk Acid Drink Boston

This is an advertising card for a lactic acid and honey beverage called Lactart, produced by the Ayers company of Boston, Mass. Based on various references, this product was produced for only 5 years, and this card and product name is from 1885. The card is in very good condition, but it was glued in a scap book with pieces of the scrap book still attached. This is a nice card to match to a dug bottle with this name.
