They are both fakes. You could charitably call the magazine a reproduction, but it isn't being represented as such so it is a fake.
There is a subtle difference between the Simpson mag and this one that is visible on the left side of the magazine...the slot on the ebay mag is too short. The other tell is at the top of the spine of the magazine, but there isn't a view of the Simpson magazine to compare it with.
