With so many old photographs coming our way now it is time to start a new feature here at Palomar Skies -- Palomar History Photo of the Week.
That is a warning sign of the side of the building that would eventually house the 200-inch Hale Telescope at Palomar Observatory. Perhaps it is a "sign" of what is to come in this new feature.
On the back of the original photo, which comes from the Family of Lee A. Farnsworth, Jr., was written "1 June, 1937 by Waterson".
Thanks go out to Observatory docent Richard for scanning this and many other images for us.
