Here’s an ad for Pabst Blue Ribbon beer, date early-mid 1940s, I think, going by the pageboy hairstyle. A time when beer ads featured classy lassies wearing more than a bikini! (Artist placed the lady sitting way too far down the harp, incidentally. And sitting on the wrong side of it! Sorry, that’s my musician pedantry at work. )

Not sure exactly what this one’s about, but possibly hand lotion, as the copy reads “Reason for calluses on slim hands – harp playing”. Again sometime in the 1940s, and this time she’s on the correct side of the harp and at the right height!

Here’s one for Bufferin for arthritis! 1950s.

And lastly for today, the harp being used for its connotations of elegance in this ad for wallpaper and furnishing fabric by Sanderson of England (click to embiggen). This was from a 1952 Australian House and Garden magazine.
