Brown Barnes Bell
This photograph is more difficult to date as the front clearly states that it has been "copied" by Brown, Barnes & Bell. The address on the reverse of this Carte de Visite would, therefore, only help with determining when the picture was copied not when it was taken.
 
A printed date, as part of the advertisement on the reverse of the carte, says 1873, so it can be assumed that the photograph was copied some time after this date. The addresses for Brown, Barnes & Bell is given as: London - 222 & 220 Regent Street,Cheapside, Liverpool - 31 Bold Street, 87 Lord Street, & 34 Castle Street.
Like the previous photograph, this one also has the printed date 1873 on the reverse. However, this is not a copy so it can be assumed that the photograph was taken after this date. The addresses given for Brown, Barnes & Bell are the same as the previous photograph.
This vignette style photograph possibly dates from the  1880s. There is a bit more information on the reverse of this photograph - as well as the addresses: 31 Bold Street, 34 Castle Street, 87 Lord Street, Liverpool & Durham Hall Bootle, it also states that Brown, Barnes & Bell are the successors to Vandyke & Brown.
Like the first two photographs, the printed date on the reverse implies that it was taken after 1873. The addresses are the same as the first two photographs.
Another carte de visite stating that Brown, Barnes & Bell were successors to Vandyke & Brown. Premises were at 31 Bold Street, 34 Castle Street, 87 Lord Street and Durham Hall, Bootle.
