The Mark

The Lockup

The full lockup pairs the mark with a vertical divider and the tagline "why not." Use this version when space permits and context requires identification.

Signature Colorway

The signature version uses white letterforms with a Seed Gold dot on the period. Use this as the default for dark backgrounds.
