Park Ranger ledgers, inspired by farmers' pocket ledgers . . . Wrapped in the mad-for-plaid designs from thermoses and coolers of the 1950s, these shirt pocket-size notebooks are a great place to jot down everything from the contact info for summer camp pals to details about your adventures: past, present, and future. 3.75 x 6.5 inches, lined notebook with back flap.
