Welcome

A very long time friend presented a picture .
And nothing , but after some time he started to demand it back as a kind of value.

Can someone suggest how you can determine its true value and whether it is possible to apply it to recognize the author (signature is).

Either this is just another product that represents value only for the author.

Please check with any information darivshego picture fails.

Thanks to all who give at least some some information .
