KC is right !! As long as she is taken out carefully, and the box is not torn or otherwise damaged, it is fine to look for the mark, then just put her back !! Collectors would be the first to look at the back of the head to see who made her !! How else are they going to find out !! Trust me,,,even they do not know all the makers marks and the label is no help !! They do reasearch same as we do !! I have looked and have not found it yet even in some of the German doll sites !!
