During a ceremonial welcome in Berlin, Queen Elizabeth II was presented with a painting of herself alongside her father, King George VI by German President Joachim Gauck.
The Queen who was baffled by the painting asked: "Is that supposed to be my father?"
"That's a funny colour for a horse" - she added.
Her questions prompted Gauck to ask "Don't you recognise him?" and she replied: "No".
The painting which pictured the Queen on a pony while her father watched was by artist Nicole Leidenfrost.
The painting, which commissioned the beginning of the Queen's visit, was produced from a photograph taken in 1935.
