Last week we went through the artisan market near Cabildo and Juramento (Buenos Aires, Argentina). In one of the stalls, an artisans was making small glass animals using colored glass rods and a torch. For ARS$20
(about US$2) he made a blue glass dolphin for my daughter (she chose the color).
It's a very interesting show and it's a nice souvenir.
