I apologise for my late response I have been away all day. FredNerks has the most complete collection of photos of Jr and I sent him a link to another kindergarten picture which is of a much better quality than the one linked above. I was interested in finding an clearer picture because of the purported Nordyke twin connection, after I had read the article which accompanied the aforementioned blurry picture.
