Here is the tough 1976 English's Chicken lid of Brooks Robinson. Brooks was part of the group of 10 small lids issued. There were also three larger lids which included Jim Palmer, Ken Holtzman and Mike Cuellar. The larger lids aren't too hard to find and show up much more often than the smaller lids. In my opinion, Brooks is one of the tougher small lids to find.
