I think you're right, Crashryan, and I’ve now seen a couple more stories where Lacey did Random's heads – #64 Five Lives of Mr Quex, and #91 Mystery of the Milky Way (for another artist). It’s particularly bizarre in the case of Turner and Lacey because their styles are chalk and cheese. It was a different matter when Lacey shared stories with Selby Donnison because their styles were reasonably harmonious. The bright ideas of comics editors are sometimes difficult to fathom.
