I noticed the color also, you can call it butter or margarine I have no clue what was used to color it. I am color blind but the deer? does not look right for a white tail either. My brother sent me the photo a few years ago, Edwards county is north west of Kerrville. Big country with big ranches out there. Deer feeders are common there, corn and other supplements are feed to increase body weight and antler size. Many imported deer and deer like animals are raised up there for sport hunting. The animal looks a little puzzled by the joke also.
Very little farming is done up there so no worry with antlers puncturing tractor tires so big antlers are considered a good thing.
