Jean-Pierre, You mentioned some photos of children's toys made out of rubbish. Why not attach some here as a springboard for discussion?
Are you aware of the work of John Milton "Jack" Roberts? Children's games, riddles, and other forms of expressive culture were among the topics covered during his decades of research combining ethnography with use of the Human Relations Area Files (HRAF).
Hello Jean-Pierre, My name is Maria Krom. I did my first research project in Portugal (where I am currently based and doing my PhD in Anthropology) between 1998 - 2001 on traditional toys made from waste products and natural materials in the rural south (Alentejo). Together with my co-workers at the local development organization we organized two small, local exhibitions on the subject and I wrote a small booklet (unfortunately only in Portuguese). We also organized a workshop on the construction of these toys for local female seasonal labourers. One of my observations in the booklet was about the relevance of Levi-Strauss' concept of 'bricolage' and the production method of the 'bricoleur' in relation to the way these toys were produced.
