Sheena #0 will have eyes on it next week when it comes out because of the 1:100 J Scott Campbell Variant coming out. However, there could be another cover to look out for.
The 1:25 Moritat variant cover could be a good grab too, if you see it, as Diamond has announced allocations for the book as a result of demand. You can see the full retailer notice below.
There is also a J Scott Campbell Regular cover for issue #1.
Not been in allocated in UK, my order still says full amount
Hopefully it remains that way, you would have probably gotten the same notification I would imagine.
