Hey AXO Alum (and other AXOs)....
Have you looked in music-themed catalogs, like The Music Stand or Music Treasures? I have seen lyres in those catalogs. (I am a music major and musician of 11 years, so I know where to find these things

) I know that The Music Stand at least used to have pretty lyre engravable Christmas ornaments. And Music Treasures used to have lyre vases. Look up those catalogs!
Oh, and besides our red rose, our other symbol is the pan pipes. Yeah, trust me, it REALLY doesn't get harder than that.
