and, the stripes do come and go... We didn't start wearing them til the 30's, and in the 90's, early 00's we wore bloody flourecent yellow (not gold)
I posted about this a while back (searched but can't find) but we had quite a few different jumpers, and colours, in our early days. In the early 1900s we even wore what was effectively an Essendon jumper!
According to http://www.footyjumpers.com/ , the b&g stripes didn't make an appearance until 1950.
