Lovers of all that is holy in the East End of London are being asked to raise £12.5m to ensure the last self-portrait of Dick Van Dyke does not stay in the UK.
The photo taken by the American Dancer/Actor/Comedian shortly after he filmed Mary Poppins, possibly with the assistance of an expert in 1965, has been described as "one of the only and most pitiful self-portraits" in Van Dyke's inventory.
Recently sold to a collector who wishes to keep it on display in Lambeth, it has become subject to a temporary ban, obtained by authentic cockneys.
The National Portrait Gallery has three months to raise the cash to buy it and export it to the US.
It has already secured £1,523.50, including a £500 grant from the Art Fund and £1000 from its own budget.
The painting will go on display at the gallery in an effort to convince all who see it that it probably would be best returned to Mr Van Dyke, far far away.
