There are quite a few replicas out there, but if you have handled many tins, they are pretty easy to spot, even in a little photo.
They are often honestly described, Dodo Tins, etc. But I have seen serious sellers mis-describe them and even worse, serious buyers bidding on them. (back when ebay displayed the bidders ID)
Dodo tins must be coming up for 40 years old I guess. So perhaps they are collectable in their own right. But to describe them as cigarette tins, when they are novelty tins should be against ebay policy.
