Lc. Hsinying Skies actually looks closer in lip form and coloration (Puppy Love x Lc. Sierra Skies. It was registered in '98 - I don't know if that's too recent or not, BD.
There are actually 58 registered Puppy Love crosses, and only a handful have pictures. Ann Akagi is crossed with nobilior, not walkerania. And definitely not Angel Heart - that has a white splash stripe up the middle of the petals on the half dozen different pictures I have.
BD, I can't post any pics from Orchidwiz, but I believe you have the DB. Check out the photo for Lc. Hsinying Skies. It's the closest I've seen.
