Three different styles. The first image is rather typical of downtown Buenos Aires, where small, sparsely decorated cafes dominate.
The second image is of another ubiquitous site in this city, the kiosco. What the bodega is to the Bronx, the kiosco is to Buenos Aires.
And the final image is of yet another common city site. Hardware stores, as well as tire and paint shops abound, all helping to support the Argentine do-it-yourself attitude.
While all of these storefronts are of a common type, I think that these three have something special, whether they know it or not.
