c.1908 - Early Postcard Picture of the Rock at White Rock, B.C.
I saw this same card on eBay with a date of of 2 May 1915 written on the back along with this message - "This is the stone from which this place got its name. We are getting quite round shoulders looking for agates amongst the gravel on the beach. I found a couple of nice ones this morning. We walked into Blaine (Washington) after I got here yesterday afternoon."
