The DINGWELT on-line picture catalogue offered for exchange 12 representations of
used things with a short story as certificate. They display pictures of the things and are
independent photo art products in the shape of digital collages.

Clients could select these picture articles and offer own used things for them in
exchange by (package) mail. In principle any offered item was accepted, only a short,
hand written history had to be sent in with the thing.

In return, the participant received the picture from the catalogue as signed,
laminated digital printing with its certificate. The exchange story with the exact data
(edition number/ date/ signature) at the back of the printings has formed the certificate.

The exchanged things with their picture and story were listed and published on-line in
the COLLECTION. Thus, the 12 art printings became articles of value and symbolic
representations of the "thing world". >>
