The logo for this brine bath usesChurchward Design 70Chisel, one of the numerous variations from this extensive display series by Joseph Churchward.
The white dimensional letters above the entrance are in a solid style from the same family, with a customized or alternate 'S'. Note the difference in spelling. Here — and on the website, at least most of the time — it is "Solebad", with an extra 'E'. Maybe the name was changed at one point, but as Churchward Design 70 Chisel is not available in digital form, the logo couldn't be updated easily? In any case, the 'E' on the siding is not from Churchward Design — it lacks the rounded bottom left corner.
