If the card looks at all familiar it's because it is. This is the exact same picture and message used for Catherine's reply last year.
There is no way to tell them apart. I was comparing the two, and I mixed them up. I was luckily able to figure out which was which, because one of them had gotten slightly dented in the mail, and I could match the dent with the dented envelope, which of course has a postmark on the date and other distinguishing features (See Below).
The picture was taken by Arthur Edwards during the Cambridges visit to Only Connect's Head Office on 19th November 2013. Only Connect works with ex-offenders and young people at risk of offending to give the the skill, tools and opportunities to develop and pursue their life goals in a productive way.
This is quite a old photo (26 Months old), even old for last years reply (14 Months old). Of all the photos I've gotten from various royals, Catherine's Birthday replies (and Duchess of York) are the only ones I've gotten that have pictures over 6ish months old. Usually the photos are fairly recent.
The envelope looked just like the usual. But what was most interesting is it came in an envelope with William's monogram on the back. Catherine's mail usually comes in envelopes with her Golden Monogram. It was either a simple mistake, or they ran out of envelopes.
It would have been nice to see something new for her Birthday reply. I had been hoping for a picture of her becoming Honorary Air Commandant in December. I though that was a really important/ defining moment for her in the last year.(besides the birth of Princess Charlotte).
The Cambridges have a habit of sending out the same messages on their cards every year, although usually the picture is changed up, so you have something new. Or they will send out the same picture, but for different events, so the message is different.
A lot of Royals will vary their message slightly year from year. This can be a little different wording or simply simply changing 30th Birthday to 31st Birthday.
