Police think "an Oasis fan" may be responsible for breaking into an art gallery to steal a picture of the band.
A window was smashed at MASA-UK on Bolton Street, Bury, Greater Manchester in the early hours of Monday morning.
The black-and-white painting by Olga Tsarevska Loma of the Britpop group is inscribed with 'otz2013'.
Referencing Oasis songs, PC Katherine Gosling said she was not aware of a "master plan" behind the theft and that "some might say" a fan was responsible.
She said: "This was the only piece taken and some might say we are therefore looking for an Oasis fan - similarly it may have been stolen to order.
"Regardless we are keen to find it and return it."
