The first and only five-fold card I've seen. It's a souvenir of Bois Blanc Island ("Bob-Lo") just off Windsor, Ont., which served as a big amusement park for residents of Detroit. On the reverse is a printed description: BOB-LO.

The Island is owned by the Detroit & Windsor Ferry Co., comprises 225 acres and is equipped with a Casino, Dancing Pavilion, Athletic Field, Bathing Beach and similar conveniences. The fine steamer Columbia covers the run several times daily. The card was posted at Amherstburg, Ont., on July 12, 1911 at addressed to Att'y. W. N.
