Here is some history about the Allen & Ginter Cards:
In 1875, Allen & Ginter produced the first cards, commonly referred to as “baseball cards”, featuring hand painted portraits of elite sports players. Although baseball was the most common sport showcased, Allen & Ginter opened the eyes of the world to other sports as well. They even produced non-athletic cards of Indian Chiefs, Actors/Actresses, and US Presidents. In 2007, Topps decided to bring the historic trading cards back into circulation.
I plan on picking up some of the cards for board members and also the other cards in the "Uninvited Guests" Set if the price is right. These cards are a special insert which can make these cards rare and pricey at times due to Set Collectors gobbling these up. Ill keep you updated on the other cards in the set when I get more info. These are coming out in Mid July.
