help a hero celebrate their birthday

I bet you've all heard about this inspiring man. He has raised millions for the NHS by walking in his garden. Did you realise though that its his 100th birthday on the 30th April? Sadly his birthday party has been cancelled due to the lockdown, but you can help him celebrate his landmark birthday by sending him a card.
 
You might want to tell Captain Tom how impressed you are by his fund raising or thank him for his effort at this time. 
 
Draw him a picture, send a message and help this Army captain enjoy his 100th birthday!
