Antique Watermarks

Second example

This is an example of a wire watermark from the same book as the preceeding example. This mark, if viewed in its entirety, would probably be similar to the previous example, being a vase with stylistic flowers. The difference, though, is in the letters which are included in the front of the vase. In this case, there are three letters: "R". "L" and "C".
