Photographing the glue residue that remains when signs or notices are removed became the unlikely obsession of Wellington photographer Alan Knowles.
He's even come up with a name for them - "Glueglyphs" - and has launched a book of his images at the biennial PhotobookNZ Festival at Te Papa yesterday.
Alan's past photobooks include ones about biscuits, sports, and Wellington city with an emphasis on its wildflowers.
Alan Knowles talks with Lynn Freeman about Glueglyphs.
Glueglyphs is published by Wai-te-ata Press, Victoria University of Wellington.
