A World War Two veteran who asked to be sent 100 cards for his 100th birthday says he is "really excited" to have received thousands from all over the world.
A photograph of Joe Cuba holding a handwritten sign has been shared thousands of times on social media.
It reads: "I'm a WW2 veteran who will be turning 100 on 2 March 2019. I would like to receive 100 birthday cards."
So far, he has received 10,000 cards - and his birthday is still days away.
Joe told BBC News: "I really didn't expect all the cards. I got a whole bunch of them - and I couldn't thank everyone enough."
Stephanie Veitenheimer, who works at Brookdale Midwestern Community, where Joe lives, in Texas, US, made the original appeal.
She told BBC News: "I asked Joe what he wanted for his birthday and he said, 'Nothing really, just happiness,' so I said, 'Well, why don't we get you 100 cards?'"
Puerto Rico, Guam, Germany and the UK are some of the countries Joe has received cards from.
His post is being placed on tables in an empty apartment at Brookdale Midwestern for Joe and his daughter to look at.
Stephanie said they had also heard from people in Japan, Australia, New Zealand who said their cards were in the post. The reaction had been "just mad", she added.
