new postcard (10-6-2012)

I bought this postcard in the flea market of a neighborhood of my city. The postmark, as you can see in the back, is dated in Madrid the 21st of october of 190?. I don't know what is the number left :S

103

In the back is written: "Querida Olimpia; tengo que contaros cosas muy célebres de las clases y de nuestras condiscípulas. Ya me contarás del aparato magno que compró padrino. Te quiere tu sobrino Ramón" traslation: "Dear Olimpia: I have to tell you  very good things about the classes and our schoolmates. You'll tell me later about the great appliance that godfather bought. Love you your nephew Ramón"
