This was free at my local library but worth picking up not just because of the message - plant trees to save the planet - but also because of the design. It is very graphical and also reasonably long so will fit into most of my books with an edge at the top that will make it clearly visible. Sometimes free bookmarks can be a bit of an embrassament if they are spotted on the train by other passengers but this one is okay and for now at least is going to be used next week until it gets too dog eared and has to be recycled.
