The Edward Pettengill collection consists of four photographs and an invitation to the 1895 MAC Junior Hop. The invitation probably belonged to Perry Holden. The photographs include a group portrait probably taken around 1890 or 1891 when Edward Pettengill was at Michigan Agricultural College. Edward Pettengill is labeled "Edd." The other photographs include a portrait of Berto Holden in military uniform, 1892; Perry Holden; and a man identified only as "Mr. Holden," who, the donor speculates, may have been involved with Michigan Agricultural College.
