Whaling Poetic

I bought a pile of dusty books for three bucks at my grandparents' auction. This week, Chris O. was thumbing through one of them, an 1879 edition of The Poetical Works of Thomas Moore. She found four-leaf clovers and various slips of paper, including this ad to see The Monster Whale. We're doing some research, but we think it might be from the Chicago World's Fair, 1893. Nice bookmark, but the reader only got through about one-third of Mr. Moore. I wonder if he/she went to see the whale.
