The 36 photographs in this book, by Eduardo Machuca, show a sample of Armando Alanis' street poetry work in the city of Monterrey, Mexico. Armando has been painting unused street walls with white and then writing with black paint, short poetic messages that capture the attention and imagination of drivers and pedestrians alike. His work is, however, ephemeral. Walls get painted over by someone else to announce something else. This endeavour is now close to its 15th year, in which Armando has painted close to 5,000 walls. Walls' poems text translated into English.
