Paddington Bear has been the official Mascot for the charity Action Medical Research since 1976, when Michael Bond the creator and Duncan Guthrie the founder of the charity first met.
Action Medical Research is a wonderful charity that has been running since 1952. "We're funding medical research to beat the diseases that devastate the lives of so many of our children." The charity have funded medical breakthroughs including the polio vaccines in the UK, ultrasound in pregnancy and the rubella vaccine.
In order to mark Paddingtons Birthday Action Medical Research wants everyone to share their sandwiches with them. #Shareyoursandwiches
So with marmalade being our little furry friends favourite filling, it is time to share yours on Twitter, Facebook and Pinterest.
