Underneath this breathtaking composition are the signatures of the participating members as follows: John M. Ward, T.J. Keefe, J.J Gerhardt, Wm. Ewing, Roger Connor, Daniel Richardson, Michael Welch, Michael Dorgan, Jas. H. O'Rourke.
If we are currently fantasizing, I'm sure I could add some names from the same timeframe, but the list is pretty awe-inspiring as is. What a great item.
