I was wandering the web, looking for a better photo of a coke bottle logo to fill in a spot that I couldn't see on my own photo... I came across Sally Tharp's work. Just a teeny sampling:
Among other things, she does very large bottles of all kinds: http://sallytharp.blogspot.com/
Her pieces are impressive hanging at her gallery show.
So, after seeing these pieces I have now decide not to do the coke bottle. Her glass is perfect!
