While thanks for trying - I haven't been able to find this exact piece anywhere on the Internet.
If someone can tell me how I can upload a photo, I will. Or when I find the time I can post it on a web page.
In the meantime, here's a description of the image on the vase. It's nothing like the one in the link you posted.
There is a woman looking out a window that has a red and white striped awning. She's looking at 3 people on the sidewalk. One is a man with a walking stick, a white with green polka dots coat, yellow plaid pants and a purple derby with a yellow flower sticking out of it. He is arm-in-arm with a woman who is dressed kind of scantily - off the shoulder dress - green and white striped bodice with a pink frilly skirt and green and white striped hat with a fishnet veil in front of her face. The 3rd person is a woman with a purple dress and a wide brimmed flower hat. Down toward the bottom are the initials m.l.
Thanks for any help!
