I don't think so. That bride appears to have longish dark hair. Laura had short blond hair. Plus, would be weird to keep a picture of Laura on her wedding day to Mickey when they ended up divorced.I felt like it was Laura's wedding to Mickey. The big veil. Hard to tell though
Maybe Jason47 knows. I'm combing through all the Days wedding pictures I can find and the bride in top black and white picture doesn't match up with any I've found yet.
