Starkers...turning pools into Jacuzzis for 50 years.
That 'd be 60, actually... if the times in my baby bath count for anything.
Now there's something of interest! The baby bath my mother used for me, my sister and brother was made out of paper... so no jacuzzi
Yes, PAPER! In fact is was treated paper mache with a lacquered finish and made in France in 1908... and probably worth a bit of money these days for it's historical and novelty value. My mother didn't know the exact details because some family history was lost, but she told me that the bath was given to her by my great, great grandmother Southcott, her mother's mother, who inherited it from her mother, who was a close relative of Joanna Southcott, pictured below, who received it as a gift from the wife of King George III, Queen Charlotte.

I don't know what the relationship between my mother's mother, Irene Southcott, and Joanna Southcott was exactly, but the resemblance is striking. Both were born in the same area of Devon over 100 years apart yet the similarities are remarkable. Not only did my grandmother look very much like Joanna Southcott, she also foresaw into the future and had prophetic visions. She told family fortunes as well as at fetes and fairs for charity... and sometimes, through fate, fortune and/or coincidence, one or two of her prophesies would come to pass.
Anyway,we couldn't bring the bath with us to Australia because of baggage/freight limitations, so I it is no longer in the family and therefore cannot be appraised for its value. I think it was left with a family friend who may have been expecting, and that was 45 years ago, so I don't even know if it still exists.
