The Big Potato Built in 1977 by local potato grower Jim Mauger, the Big Potato adorns the main street at the eastern end of town. It was modelled on the Sebago potato and is approx ten metres long and four metres wide. The original idea was for this structure to contain a Potato Information Centre but rising costs chipped away at this dream and in the end it boiled down to nothing. Recently the locals of Robertson have worked together to turn the surrounding land into a park to be enjoyed by locals and tourists alike.
On 6 March 2010 a group of young people adorned the potato with a very large face, to help brighten up the tourist attraction for the local agricultural show. It was built in secret during the weeks leading up to the show and even the owners of the potato and the surrounding land had no idea that it was going to happen. Sadly this work of guerilla art was torn down and damaged on its first night, but it generated enough buzz to appear in a few newspapers, several news websites, blogs, national radio and two members of the group were asked to appear on the national TV show The 7pm Project.
Despite requests to rehang the face the artists considered the damage to be too significant to rehang it, but had not ruled out repairing it and putting it back up for a future special occasions. In 2011 on same weekend in March the artists sneaked back into the village in the early morning and rehung the repaired face on the big potato. It has since been donated to the local chamber of commerce to be used for promotional/tourist purposes and has been hung to promote the Robertson Christmas in July festivities in 2012 and, with the addition of a santa hat, in 2013.
