I just finished adding 7 more images of angels playing trombone to the Trombone History Timeline and to the collection of angel-trombones on Hubpages (where there are now 112 examples). These images and several others will also be added to the interactive Google map of Trombone Art in Europe.

Early 1600s—Bologna, Italy: A painting in the Oratorio dei Battuti of Santa Maria della Vita features an angel playing what appears to be a trombone.
