A Happy anniversary banner is a decorative piece made out of paper that is designed to celebrate a couple's first wedding anniversary. It typically consists of a series of individual paper panels or flags that are strung together to form a banner.

The panels or flags are usually made from high-quality paper or cardstock and can feature a variety of designs, colors, and patterns. Some popular motifs for paper anniversary banners include hearts, flowers, and other romantic symbols.

The panels are often connected by a thin ribbon or twine, which can be hung across a wall or above a doorway. The banner may also feature lettering or other embellishments that spell out "Happy Anniversary" or the couple's names and wedding date.

Overall, a paper anniversary banner is a beautiful and meaningful way to celebrate a couple's first year of marriage, and it can serve as a lovely reminder of their love and commitment for years to come.
