I believe the elusive seahorse on the Old Point Loma GLOW piece has finally been netted. If you look at the back of the building, locate the larger of the two bushes, the one on the left side of the "porch". On the left side of the bush, facing slightly upward, you can make out a shape in the bushes that looks remarkably like the seahorse shape. Not one to jump to conclusions, I had my wife and daughter back me up, and they both concur that it appears to be the real thing. Actual credit goes to my 11 year old daughter Stephanie for locating the little guy.
Check your pieces, and if you think I'm wrong, let me know.
