My Mum used to love old bottles and would often be seen ducking behind buildings for a "poke around" in the dumps when we travelled.
But she also liked new bottles with interesting shapes and bought many strange liqueurs because she liked the bottles!
When I got into the roof of my house back in the early 90s, I found about 20 empty dust-covered VB bottles! Thanks to the builders or the insulation installers
Also, when I had to break up a concrete path, I found so much broken glass under the concrete (yes, VB bottles again) the lumps were dangerous to handle.
Great stuff, glass - it lasts so long and can be restored quite well. Very interesting examples here. Great hobby because, if you have the inclination and willingness to travel and fossick, a great collection can be obtained for free.
