there are some vague similarities here, for example the UFOnaut seems to have one eye hole very similar to the ice warrior,the head shape is similar
too
but everthing else is off
good point
the problem here is that this is a beyond obscure case, the article i linked and this thread are probally the first time in 40 years that someone paid
attention to this case, so if there are more pictures, they are either buried in some forgotten japananese newsletter about UFOs or completely
forgotten
