Lennon's first art exhibition You Are Here at the Robert Fraser Gallery consisted of a display of 50 charity boxes. The display had an interactive element of which the letter in this lot and the enclosed badge, formed a part. The 365 white balloons which John and Yoko released at the opening of the exhibition represented the number of days in the year. Each balloon had a label attached to it on which the words you are here were printed one side, and the instructions write to John Lennon c/o Robert Fraser Gallery 69 Duke Street London W1 on the other. Apparently over 100 of these labels were returned and then displayed in the exhibition. As Dorothee Hansen explains, with this exhibition Lennon, like other sixties' concept artists ...used extremely simple artistic devices to address complex questions of existence, time and space...The words "you are here" would be just as applicable to the situation of the finder [of the balloons] as they were to the exhibition visitor... [and] ...could also create a link between Lennon and the finder. By replying to the message, the finder would also be "here" at Lennon's exhibition.... The badges which were created for the exhibition had a similar function ...Pinned to a lapel, they would be carried from place to place and read by many people at different locations.... The exhibition, which John dedicated to Yoko, came about as a result of her prompting. At the opening she commented: ...John has these crazy ideas all the time...He just didn't use them. It was just a personal joke for himself. He has about 20 ideas in 20 minutes. So I say 'Well, that idea is good, why don't you just do it?' and he had never thought of actually doing it, physically. The point is, when you do something, something happens, the concept is simple, but then you get all sorts of reactions and you've started something"...
