Underground advertisement. Context.

This is an image I found whilst looking at another blog of mine. It seems to put my project right into context. It shows that most of the adverts on the underground are depicting things which would be expensive... and for people using public transport, this seems reasonably ironic.
I liked this image as it was unusual, and seemed to fit perfectly.
I am not trying to sell anything... in fact what I am promoting is totally free. Comes from within...
