Looks fine to me without even having to look at other examples again. This one of mine is probably from the same kind of period and has almost the same inscription:
Thank you! I don't honestly know when my example was signed but I would guess it is more likely from the 80s than 70s. I may be able to find out more exactly as I know who the "Andreas" in question is and I could probably ask him through the mutual friend I bought it off. That won't happen any time very soon though.
oh it doesnt matter, I am just curious as her later day sig in the years before she died was very different to the one I posted which is why I was thinking late 70s or early 80s
