Weidner Catalog lists 15 b+w embossed postcards (#19-#30, #80, #82, #150), some with several variants. Early cards (1902-1904) are by Goeggel & Weidner, later cards are by Weidner. Most of the embossed card images also appear on non-embossed color Weidner cards with different stock numbers. The embossed cards are particularly striking, but sadly a scan does not capture the tactile character of the embossing. To allow writing on the card, the back is a separate sheet glued onto the embossed front.
These cards show Golden Gate Park scenes.
