Wild Grey Fox Ltd. “Thanks for All the Fish” greeting card features Clyde the Otter artwork. Blank greeting card with envelope, clear compostable bag. Paper. 5" x 7". This is what Nikki has to say about the artwork "So Long and Thanks For All the Fish": “Meet Clyde the River Otter. Clyde was a famous, or rather infamous Otter, who lived at Wellington Zoo. in 2000, he was relocated to a private zoo for 'wayward animals' in Australia after one too many escapes resulted in him being found hiding in a Wellington apartment for nearly a week. 'So Long and Thanks For All the Fish' seems a fitting title for this little rascal."
