This is a Wedgwood 1st Edition, University of California, Berkeley Campus, Henry M Stephens Memorial Hall (1923), collector plate. This piece is blue transferware, and like the name states, shows a picture of The Henry M Stephens Memorial Hall in the center. Around the outside there are various other small renderings of campus sites.
This piece is authentic Wedgwood. It has the Wedgwood mark and pattern number. The plate reads that this piece was manufactured in 1932. I believe that Wedgwood manufactured the plate and the design was created and added by G. Elwood Hoover / California Plates. Replacements, Ltd. is selling these plates for $169.99 each.
This plate is in excellent condition. Take a look at the pictures, and if you have questions, please e-mail.
