(Arkansas River Route 5999) Steamer Isabel, blue octagonal handstamp on folded bill of lading wrapper endorsed "with freight" and addressed to Waterford Plant., Arkansas River, docketed "Isabel" at lower left; some aging at left corners, F.-V.F. Milgram No. 655  Estimate $200 - 300. In 1848 route 5999 was contracted for the mails between Little Rock and Napoleon to Lewis Snapp of Little rock for $8,777 per annum. Neither Klein or Milgram list any vessels operating on the Arkansas River, from the cover illustrated listed as Klein 257 and Milgram 655 some of the Mississippi Name-of-Boat vessels did go onto the Arkansas. The "Isabel" was built in 1850 and lost in 1854, thus bracketing the date of this cover. $0 (Image)
