Antique 1900 Stereoviews of Boer War Lord Roberts General Pole Carew Underwood & Underwood

This is a lot of four antique Boer War stereoview photos produced by Underwood & Underwood, circa 1900. included are Lord Roberts, General Pole-Carew, soldiers in the Orange River trenches holding back the Boers and a soldier looking into the Orange Free State, over the 12th Brigade Camp and Signal Hill. All four cards are sepia toned and in very good condition - they have a vertical curve, but I think that this is normal for stereoviews. Each measures 3 1/2 by 7. These are wonderful collectible Boer War stereoviews.
