Snoopy Charlie Brown Artwork Sowa & Reiser numbered 375/500 Peanuts Chair.  signed on the matte by Sowa & Reiser.  Hand painted etching process. This was once professionally framed.  It is no longer in the frame.  The artwork is fine. The back of the matte is separate from the front and has tape on it from the framer.  The certificate of authenticity is in the enveloped which is attached to the back matte. The print is still attached to the front matt.  The matt measures 15" x 15".  The picture opening measures 6" x 4.5" . The matt opening measures 9" x 7".   All measurements are approximate.  This should be very easy to reframe in my opinion.  I make every attempt to ship within 24 hrs of payment.  Same day shipping if possible.
