Yes, the pineapples (Ed; Is that what they are called?) are made of bronze, but are they really worth that much, to risk so much to nick (to steal in UK English) them? And that just shows you the state of crime in the UK and in the socialist dump that is Glasgow and Scotland, that these thieves feel as if they simply will not be caught - and they probably won't be.
Apparently, two of these "works of art" (now we know that they may be made from copper), were stuffed into some person's auto, before they made a get away!
All I can say, is it must be some size of motor ("car" in UK English)!
