The press release says:

The May 2014 edition of ZOOMER Magazine hits newsstands next week with an excerpt and stunning photography from Highgrove: A Garden Celebrated by HRH The Prince of Wales and Bunny Guinness. This Canadian print exclusive and royal invitation to the grounds of Prince Charles’ beloved rural retreat comes as he embarks on his 17^th visit to Canada in May.

“We are honoured to have HRH The Prince of Wales on our cover,” said Suzanne Boyd, Editor-in-Chief of ZOOMER Magazine. “The world has caught up with Prince Charles. In the ‘80s he was like a voice in the wilderness, presciently sharing his progressive views on all things environmental from how best to nurture plants to organic farming to conservation. Thirty-four years later, it is most fitting he would be sharing his gardens.”

Quite a celebrity cover, and the timing is perfect. Look for this one to sell!
