Bathing Pool Towel
"I mentioned in my previous email
that I used to have a couple of towels, which I had assumed had been thrown
redecorating entailed digging out dust sheets etc, and one of the towels was
in with them. The towels, like the sign, were retrieved from a skip in
find the second one, so this may be the only Portobello Open Air Pool towel
still in existence !! OABP stands for 'Open Air Bathing Pool',
as if you couldn't guess."
