T it sure looks like a horse but maybe a graver.Very interesting for sure. Our history with horses is limited here in Tennessee thinking maybe DeSoto was the first to come through with them ? We did have minature horses and camels about 12,000 years ago or little later though. I guess if they saw desoto they would have been in awe of such a large docile animal and would have wanted a copy of it,,,,anything is possible sir. I know they snatched their conquistador helments every chance they had haha.
Glad you are doing better and have enjoyed your post and hopefully you will be released to drive before to long.
