Dear Sirs,
graphics Basmanova sign at the exhibition in the Russian was. Drawing on the same auction world was passing. Although it is not enough. That's got medium-sized picture painted in tempera. Whether once it is pulled, but the signature left on the end of the subframe. Although the 'new nails' new do not seem ...
My question is this. Could the schedule to work with tempera? I want to see his daughter do not get to the attribution. She will not let reporters

All the best
