From an architectural perspective--and you touched on architecture--I took a look at the stamps that were issued. These lighthouses have very different architectures, whether they're east or west coast. It's based, I guess, on access to local supplies, whether they're inland or beside some of the freshwater lakes. We've got ones that appear to be built in circles; they may be built out of stone.
Out of all the different architectural styles, how many different varieties are there across Canada? Can anybody comment on that?
