I used to have a MnM (actually I’ve had two, but that’s another story), and it was a Mk 1 that I bought used. In the original packaging as well as manual etc, was an Elektron promo flyer.
I don’t have it now as I put it in the box when I sold the MnM, but I just found photos of it that I took. It’s quite intriguing to look at in retrospect, especially the item labelled as ‘Teenage Audio’. I’m not versed enough in Elektron history to have realised there was some kind of link between Elektron and TE, but it certainly looks like there was one
