1921: Independence Jubilee 2 centesimos carmine and 10 centesimos violet, tied by barred cancel to registered envelope from Balboa to New York, reverse departure “BALBOA REGISTERED 2 JUN 1923”, transit “NEW YORK 6-11 1923”, from there scarce violet five-line “Intercepted by request June 12 1923” and “Return to sender N.Y.P.O Reg. Div.” along with oval “RECEIVED Registry division JUN 12 1923” on reverse, final return delivery with cds “BALBOA REGISTERED JUN 20 1923”. The 2 centesimos with faults, some minor soiling at top, otherwise fine. A rare and noteworthy specialist usage (Scott-Nr. 61, 63)This very unusual UPU service, created at the UPU meeting of Lisbon in 1885, provided the opportunity for senders to have their mail recalled to them, or redirected elsewhere, before original delivery had been made.
