The front of the envelope is the usual for the British Royals, featuring the red postmark from the Court Post Office at Buckingham Palace. On top of that is a postmark from the Mount Pleasant Mail Center, where most international mail in the London Area is processed before heading to Heathrow Airport.
That postmark includes the message, "Royal Mail supporting youth mental health with Action for Children." Action for Children has been the Royal Mail's official charity to support since 2017.
The back of the envelope features the Prince of Wales feathers.
One interesting this is the letter says May 22nd, but the envelope is postmarked over 2 weeks later on June 6th.
I also noticed that the letter doesn't use the term COVID-19, which is how Clarence House has been referring to it on social media, instead, Claudia used the more informal term "Coronavirus."
The letter says:
Dear Miss Daly,
The Prince of Wales and The Duchess of Cornwall have asked me to thank you for your letter of 9th April, which you so kindly sent on the occasion of their 15th Wedding Anniversary.
Their Royal Highnesses are most grateful to you for taking the trouble to write as you did. The Prince of Wales was enormously touched by your kind words of support following his recovery from Coronavirus.
Their Royal Highnesses have asked me to send you their very best wishes and they hope that, at this difficult time, you and your family are keeping safe and well.
Yours Sincerely,Claudia Spens
