Rare 1876 trade card, dating from the National League's inaugural season, featuring a woodcut illustration of a game in progress at the Boston Base Ball Grounds. The card was issued in promotion of Washburn & Moen's "Barb Fence Armor," which can be clearly seen atop the stadium fences in the illustration. The reverse features a glowing testimonial, dated September 1, 1876, from Boston team owner N. F. Apolonio [sic] extolling the cost-saving benefits of the company's product. This is only the fourth example of this particular trade card we have seen and the third we have offered. All material dating to the National League's inaugural 1876 season is rare and this particular piece, which relates to the Boston club (the oldest franchise in the Major Leagues), is especially desirable. The card (6 x 3.375 inches) displays very light foxing and is otherwise in Excellent condition. Reserve $200. Estimate (open).
