Books on poker and poker sets like this one, housed in a handsome oak container, attest to the fact that Henry Clay Frick was an avid poker player. In an unpublished memoir, his daughter Helen recalled: "Once a week, my father had a group of men friends come in for poker after dinner. I had the important duty of arranging the chips and took great pleasure in doing this, feeling my part was a very essential one. . .They played in the breakfast room, and the following morning the room still retained the odor of cigars which they all smoked."
