David Newbitt's commentary, on a photo of his that has been removed:
Another shot from our trip to Osborne House. These are the wheelbarrows used by Queen Victoria's children to tend their vegetable plots. They must have been non-sharing children, as each has his/her name painted on them (Pss. H is Princess Helena, Pss. R is Princess Victoria, Princess Royal and so on).
Apparently their father, Prince Albert, encouraged them, and bought their produce from them at going market rates!
