Large Antique His Master's Voice Victor Nipper Dog Lithograph On Canvas

This depiction of the famous antique painting "His Master's Voice" by Francis Barraud become synonymous with the Victor Talking Machine Company who produced phonographs and records. It has the appearance of a painting but i believe it is what is called a lithograph on canvas. This is the first time i have come across this particular item which has the title,artists name and patent information along the bottom. I do not see any reference to Victor anywhere and as you can see other than crackling to the finish there is a tear in the canvas along with some other age blemishes. This thing is really neat with the look of a real painting and would be a great display piece for anyone who collects phonograph related memorabilia. I am guessing it possibly dates to the 1920's era with the frame measuring almost 34" x 28" in size.
