The Pasadena Showcase House for the Arts celebrates its 65th birthday while observing the 50th anniversary of its national fundraiser, Showcase House of Design. To honor those who have given their time and effort to the organization, the House has published a coffee table book called “50 Years of Pasadena Showcase Design Houses: Supporting the Arts Through Design.” The exhibition opens April 13 through May 11, and takes guests through the seven-bedroom, 10-bath country estate. A shuttle will take visitors from the Rose Bowl parking area to the unpublished location of the Showcase House.
