Haiti, Dec. 13, 1927, two West Indian Aerial Express flight covers, American Air Mail Catalogue #WI-5 and WI5a, both are signed by Pilot B. L. Rowe.  One is from Port Au Prince (Haiti) to Santo Domingo (Dominican Republic), the other is from Port Au Prince (Haiti) to San Juan (Puerto Rico). Most of the flown covers were lost in a tropical hurricane shortly after the flight, so these are very scarce. See scans for exact condition. Free shipping to any U.S. address.
