These gentlemen seem to have had three addresses in Pollokshaws road at various times and it is not clear to which of these these cards belong, or indeed if all of the various addresses are in fact separate locations. The lady with the doll-like child is earlier than the smart young lady, and both are on gilt edged and chamfered cards, and are typical products of the mid 1890s.
The first cabinet card below has plain, square cut edges, the second has silvered and chamfered edge. Both have the same graphics as the second cdv above. These probably belong to the late 1890s, but the sequence is not certain.
