I had the pleasure of creating a custom buisness card for The Spirit-Level.
These design iterations were based on the client wanting a similar colour scheme to much of my previous work - bold while still maintaining an air of maturity.
The back of the card features basic contact information, as well as a QR code leading to further digital interactivity (a linktree with social media and booking availability). Again, the back went through many more variations, but much more subtly; shades of yellow and green were tried, placedment of text and alignments used, and of course we had to find the right font.
