This is from a Hal Leonard book for classical guitar, specifically Cancion 1 by Paul Henry. Are the flipped treble clef symbols (horizontal flip & vertical flip) in phrases 1-3 typos or do they have meaning I haven't learned yet? I've tried googling but can't find anything on this. I thought it was supposed to circle the G note location, but the vertically flipped one would be circling the D note. Any help would be appreciated.

I was curious if anyone here recognized this sound hole sticker or guitar. I found it also in a typesetting publication, maybe for the company that printed the sticker. From what I researched, this was somewhere on guitar street in HCM in Vietnam. Perhaps 1980s?
