I think this is a magnificent sign, not only because of its size, but also because of the variety in its lettering and the lovely phrase (or brand name?) “electrine candles”. I can’t decipher all the words though. It appears the white writing has been painted over top of the blue. Here is my best attempt so far:

VELVET SOAP

99/100

PERCENT

PURE

ELECTRINE

CANDLES.

I can’t decipher the words in white paint. Perhaps the second of them is “DRAPER”? There may be more words in blue/purple running along the bottom, but I am not sure.
