Today I’m offering a great, interesting "Evolution set" 6 Coca Cola contour collector bottles, contour collector bottles from Coca Cola Coca-Cola evolutions - set 6 miniature bottles that show the development of the Coca Cola bottle from 1894 to today. Coca Cola has used six different types of bottle over the past 100+ years, which have been faithfully reproduced here as miniature bottles. There is a description printed on the back of the box that details exactly when each shape was used. The 6 bottles are inside a gift/collector box. (see photo) Height of bottles is approx. 7.5 cm The six Coca Cola bottles are made of glass.
