Festive images... angels playing lutes to violins to keyboards (is that a clavichord?). I especially like the angel in the top right that looks a bit like the cowardly lion (but I'm a bit odd).
Sized for 2-slide Slide Mailers (but will work well for ATCs, too).
ATC above is by Design Team Member Lynda Roddy Ozzauto.
