Small cover from "CORFU*12.APR..", handwritten "Via Trieste", to Firenze. Rate marks "1" (d) Ionian postage, "9" (kr) for the Corfu-Triest route and "12" payable on delivery on local currency. The combination of 1d and 9kr was valid only for 14 months (08/1857-30/10/1858), so this must be a 1858 cover.
