how do I send them?

the actual size is 9.5 x 12 inches with the frame it is larger

I have better images...do I copy and paste them?

Dear William,

Thank you for your request and the additional images. This is a mixed technique watercolor with gouache with the measurements of 12 x 9,5 inches. It depicts a flute playing clown. The drawing on paper is signed in the left corner with "Marc Chagall".
For an authentification of this artwork, a long and intense procedure has to be fulfilled. First, it has to be checked what the provenance of this piece is and if this watercolor is mentioned in the "catalogue raisonné". The final decision about the authentification of this piece has to be decided by the "Chagall Committee".
An estimation would be between 50.000 to 100.000 USD.
This valuation does not serve as an authentication of the work.
This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary.

With best regards,
Georg
