Is that Fowler of Salisbury, not Shrewsbury?

Most of the Shrewsbury broadsides on the Bodleian site seem to be to do with the 1822 Parliamentary election, some singing the praises of 'Pelham'. A web page says that John Cressett Pelham spent ?20,000 on his succesful campaign.

How many of the rhymes printed elsewhere were promotional or campaigning in some way and redundant after an election day or similar? Paper was expensive. Was the back blank and if so what did people write on it?
