135mm x 135mm square greeting card from Broadway, by Connor H G, our resident art monkey.
This only works if they don't need help, you know, actually opening the envelope.
Congrats. You managed to open an envelope. You're like, my hero or something. - Blank inside, for your own secret, extra special, awesome message (if you're actually giving it to someone else, otherwise, use the space wisely...)
Supplied with white envelope.
