From a practical standpoint this usually means that if you put this house in a publication about Wright, the Foundation and Conservancy will deny you use of their archival material and photographic access to their sites.
Their behavior is why you rarely see Wrights work at Florida Southern College in books on Wright despite Florida Southern being the largest collection of Wright designed buildings anywhere, one of a few examples of his commercial work, absolutely amazing designs, and actually in ordinary use…worth a visit if you are passing by Lakeland on I4.
