International Mail (11)
Another example of mail to Spain prepaid by postage stamps.
This time the letter is franked with a pair of 1/2 real
plata stamps, apparently because it weight between 1/2
and one ounce (double weight).
The letter was posted at Havana on December 16, 1856,
and arrived at Santa Cruz de Tenerife, Canary Islands,
on January 16, 1857.
Tome I, p.19: Havana to San Miguel
de Tenerife, Canary Islands. 16 December, 1856.
