This is a large antique print or engraving my mother bought from an antique store in the late 60's. I'm trying to determine who the artist might be and value of the print. Glass is original too frame.

I found on the net that this is a trade card from the late 19th Century for Dr. Jayne's Tonic. Hope you find this helpful
Description
The front of this card depicts a young maiden holding a milk pail, walking between two cows. The reverse of this card states that this is a very popular engraving of a milkmaid and her two docile pets titled "The Jerseys". (The title and upper left corner has some damage.) It goes on to state that for all pulmonary affections it is Dr. Jayne's Expectorant that is the surest remedy. When a bad cough or cold irritates and racks the lungs, the Expectorant in small doses speedily cures. Other uses are for sore throat, bronchial disorders, asthma, pleurisy, and whooping cough. Also every family at times needs a serviceable medicine for worms in children or a useful tonic for the general debility of children or the dyspepsia of adults. Dr. Jayne's Tonic Vermifuge supplies such a remedy. Presented by Wm. P. Barnett, Park Avenue and Dolphin Street, Baltimore, Maryland.
