@5teverin0 From what I can see, the bigger lettering between the middle and bottom window, by the washing powder, might be STERN.
Other than that, I have no idea.
@countdracula @5teverin0 Agreed, with "& Co." after, and the letter 'Y' just before, so likely a name, eg "_____Y STERN & Co."
@blag @5teverin0 Possibly an A before the Y. The shadow blocks part of the letter. So, it could be "A Y STERN & Co".

@countdracula @5teverin0 There are also multiple layers on this palimpsest which makes it harder to tease apart the different signs.

I had a look through William Stage's book but it's not in there.

Review of Fading Ads of St. Louis by Wm. Stage on Ghostsigns. A book about painted advertising, fading on walls.

Fading Ads of St. Louis by Wm. Stage| Ghostsigns | This stunning photograph is from the cover of Wm. Stage's latest addition to the ghostsigns literature, 'Fading Ads of St. Louis'. Stage's first book, 'Ghost Signs', remains the definitive text on the topic and so it is no surprise to find his latest work full of fantastic photography and meticulous research. In this case Stage
@blag @5teverin0 I did some looking to see if I could find something. There seems to be a lot of power washing places in St. Louis, but couldn't find anything about the place in question.
