and history of the design I call the XYZ from three slit
squares and the XYZ Ball from three slit circles. Please
contact me if you know any of this information is
incorrect or if you have any other information that

At first sight these designs might not appear to be paperfolding designs. However, they cannot be assembled without folding the pieces from which they are assembled and thus qualifies to this extent.
As far as I know the first appearance of the XYZ Ball from three slit circles is in 'Des Kindes Erste Beschaftigungsbuch' by E Barth and W Niederley, which was first published in Bielefeld and Leipzig, and the foreword of which is dated October 1876.
A drawing showing XYZ from three slit squares can be found in Eleonore Heerwart's 'Course in Paperfolding' was first published in Dutch in 1895 then in English by Charles and Dible in London and Glasgow in 1896.
The XYZ Ball also appears in 'Pleasant Work for Busy Fingers' by Maggie Browne, which was published by Cassell and Company in London in 1896. This book is an English version of 'Des Kindes Erste Beschaftigungsbuch'.
