Central & Gus greeting cards feature fanciful illustrations with equally charming backstories told on the back of the card.  For example: 

"His letters, always perfectly formatted on his trusty "Celeste" typewriter...are a delight to receive."

The cards are printed on Forest Stewardship Council-certified 100% post-consumer recycled paper.  And Central & Gus donates 10% of gross sales to animal welfare causes.
