Prothero Eyewear Business Cards

Working on concepts to include in the final brand presentation for Prothero Eyewear. Our aim with the business cards and additional stationery is to try and convey the sustainable values of the company to back up the classy logotype. One idea we've been toying with the is the rings from a tree trunk cross-section, hopefully you worked it out already but that's what the rings on the cards are supposed to represent!
