Interesting self-portraits and Kustodiev Weinstein.

Strange somehow tell "signature on the left, at the bottom" for mass production.
What is the signature: pencil in reprint?
Well this is very important, especially for the work of masters.
That it is necessary to specify optional and of each and carefully think out?
:)

You are about Rembrandt?

And about him, and Miro, Kustodiev, Warhol (here at the dedication, but not the main signature).
Something more serious than we would like, but it is necessary to estimate and guess so here's a photo ...

This lithograph.
And it clearly says - " lithography ."
Silk screening.

For example, I did not have any issues , and if they arise - to call the Dukat and find out.
They add. can send pictures , by the way , if something is not clear is the future of the bidder .

Schelkografiya - admits : everything is clear .
Lithography, etching : nothing is clear. Signature "by hand " or "in press" effect on the price of about two orders of magnitude .

It is clear that we can ask or "guess" by estimate, but is so hard to write it once?

Effect on the price and circulation series and even the number print.
All this, if you wish, of course, it turns out in the Auction House Committee , for example, to view or if someone wants to participate in absentia, so contact with the auction .
Just do not write in the catalog that is used . there is a paper version of it , as usual , more fully describes the lots.

From me it was more of a wish to those who sell mass production professional. There are, of course, and have a lot of factors for the same "image ": place of publication , type of circulation , year , type of paper , etc. etc.

But, to ask these questions , I would like to first see in black and white , is signed by the author of this specific instance. For many it is the norm. Including it is quite simply the perception of "constructive criticism" on this little issue. :)

And the one who is selling and who is buying that mass production is well aware of all the nuances, in addition, as already noted Cyril Syzran , if necessary, to all individual questions BP will otvety.Sm.razdel contacts http://www.dykat-auction.com .ua /index.php? contacts
