I have a piece of mulberry-coloured matte board which looks like it should harmonize, colour-wise, with these notes. I'd be happy to send it your way.

The main interest of the ABNCo liberation notes for me is that they form a series with similar notes printed for the Dutch East Indies, & also for Luxembourg. It makes a thematically interesting collection, although not a visually interesting one! They're very different from the occupation currency used by US forces in Germany & Japan.
