J. Gould and H C Richter del et lith (Circus Cyaneus)

The glass in what I believe to be the original frame was broken, but the frame, matting and picture are in beautiful condition. It looks like the frame and matting have gold leafing. I do know that Mr. Gould was commissioned by the queen of England to go to Australia and draw the wild life from that country. I have search and search the to find a copy of this lithograph on the web to no avail. It is called Circus Cyaneus. It has J. Gould & H. C. Richter del et lith on the left hand side, Circus Cyameus in large letters in the center at the bottom and Walter Imp. in the right hand corner. I would appreciate very much to learn more information about this lithograph and it's value of course.  I am unable to download the photo's of this lithograph.  It keeps flipping me to the refresh page. I don't know what I am doing wrong, but have never had this to happen prior.  Thanking you in advance.
