A Vintage/Retro Business Card Template.

The Blue is not a random choice of color here. It represents the stability and depth. It also symbolizes trust, loyalty, wisdom, confidence, intelligence, faith, truth, and heaven.

White represents light, goodness, innocence, purity and Black is the opposite of what White represents. The Black and White represents the concept of earth as in both Positive and Negative here in contrast with the Blue color.
If you like the project or if it has inspired you, it would be cool if you could appreciate it.
