Greetings @rubencress,
This is such a lovely idea...that after visiting your Grand Piano post.....I thought of another idea for these postcards.
How about white flowers/flower.....tulip with the green still attached with a back drop of a black Baby Grand piano or the keys?
To whom would I send it? .....good query...
Cheers!
Thank you for your idea! I think I can work something out.
