I found these dice at the antique mall today and don't have a copy of any dice guides. Can anyone identify them as to time or location? One die says Horseshoe with an arrow between the horse and the shoe. The other one is hard to decipher but I think it says Harlem. Sorry about the large scan but the printing would not be visible otherwise. BTW I used a little cinnamon to color the one die and the pips are incused.
