If we are being pedantic, I can see that the font on the repro seat tube decals needs a degree more italicising to match the 'originals'.
For example, the 'upright' of the 'R' would appear to be at about twenty degrees from vertical on the repros, and more like thirty degrees on the originals.
Having said that, a look at the picture on p.14 of this thread reveals that the italicisation of the seat tube letters is manifestly less pronounced than that of the down tube letters.. and for that matter, I don't believe that the bike on p.14 has an identical seat tube decal to the one on Joop's(?) bike on this page..
