The images come from antique books in my personal collection. They have Neptune (or Poseidon), florals, scrolls, spirals, and stylized feathers in their design. Would you like to see a particular monogram letter sooner than later? Just leave a comment with your preference.
This last monogram is something I made in Photoshop with a stock alphabet letter and a fleur de lis ornament from an old typeset catalog book. It is a png file with a transparent background, perfect for digital layering. I think it would look so pretty printed on fabric for pillows or napkins.
