Looks to me like the black writing says あんよいらず and the white writing says 軽井詠, which I'm guessing are "no need for walking" and Yomu Karui, a personal name. I'm not sure how accurate those are, though. For one thing, there are what look to be three strokes in the form of a "z" underneath あんよいらず, and for another thing, I'm not entirely sure the reading of that name would be correct, assuming I've got it right in the first place.
