      Hi All,

      I’m new to the community, and enjoy reading the “Daily Digest”…thanks in advance for your advice!

      I recently encountered a c. 1915 postcard that has “glow in the dark” properties. My initial reaction was that there may be a concern with radium, as radium was often used in luminous paint in the early 20th century. I’ve heard of radium being used in paint for watch dials, doorknobs, and other 3D objects, but I’ve yet to find a postcard example. Is this something I should be concerned about?

      I found a duplicate postcard listed here on eBay:

      As you will see, the reverse (in French) reads:

      “Expose the picture to the light, it will appear luminous in darkness.

      IMP. RAD-Brevete S.G.D.G.”

      (The “RAD” obviously stood out to me here, but I’m not sure if it’s an abbreviated reference to the printer?)

      Thanks again,
