Interesting old souvenir piece, a china plate commemorating the 100th performance of Ye Dairy Farm at the Parke (Park) Theater of Philadelphia, 1901. This is unmarked, a large (heavy) plate about 9 3/4" in diameter.
I believe it's original, almost 125 years old. The lettering is slightly crooked as is often seen in older transferware designs. And I've found very little information in general about this show, so I don't think this is a piece that was ever reproduced. It's been carefully kept over the years, and has no chips or damage.
