Love this paper with matching envelope! The sender doesn't use fountain pens, but she knows I do. They're very good representations of vintage pens, and there are little stamps and letters there in the design, too.
For a closer look, view large.
Update: Because a lot of people have already asked where she got this paper, I'll say here that I don't know where she bought it, but the copyright at the bottom reads "Peggy Jo Ackley." So that's a start.
