Sergey Larenkov shows us exactly what it is to merge present images of locations such as Lenigrad, and to combine them with old photographs of the same locations. In particular he merges those depicting the Siege of Lenigrad, the siege being of Axis (Nazi) objective.
This has the effect of forcing viewers to realise that those who are old or dead were also young once, and intensifies the realisation that such events really happened, it forces them into present relevence.
Of course what makes the images most prominent is the stark contrast between the suffering of the past, and the safe indulgence of the present; but some people feel the past is just the past and will never be repeated on any level. Yet awful things still do happen in the world, maybe not on this scale in Western culture, but there is still suffering, and it helps if we realise our own fragile mortality, and that just because times change, it does not mean everything should be forgotten or buried.
