A poster mocking actor Amitabh Bachchan on being part of the No-Honking Drive initiative of the Mumbai Traffic Police was put up in Mumbai on Wednesday.
The poster -- in Marathi -- bears the Maharashtra Navnirman Sena logo, Juhu residents said.
Contacted, party spokesperson Shirish Parkar said he was not aware of any such poster.
Last month, the MNS mocked the actor through a poster for going back on his decision to donate his agricultural land to farmers in the Pune district.
