We were walking up Lafayette Street when we found this vintage-style Western-adventure paperback novel set on the steps to a cast-iron building. (The building was near the mysteriously plain and discreet false-back-front entrance to Imperial Nine and the Mondrian Hotel SoHo.) The book seemed to have been placed on the steps deliberately. The novel is titled “Mr. Tucket.” Its author is Gary Paulsen, who has written a saga of these books for children. The cover design evokes an era of American book publishing from the mid-twentieth century.
