I can help you with that.
I will send you a postcard from the Netherlands with a nice Dutch stamp and words of your choice or mine.
The card you receive is a tourist view card from a random city in the Netherlands.
It will be a good quality card with a good looking view.
To USA and most other countries takes average 3 to a max of 7 days. But keep in mind if you live in russia or china, or simular, it can take up to 3 weeks. It's not in my control.
