I want to know the answer to the following question:
Where did a protector put a notice because of Queen Victoria's lack of public appearances in March of 1864?
All the background I'm provided with is that "In March 1864, a protester stuck a notice on the railings of Buckingham Palace that announced "these commanding premises to be let or sold in consequence of the late occupant's declining business".". Is that enough to answer the question?
