$1,234 · Horse Poster Wanted

I am looking for posters of horses for my mother in law. She is in a long term care home due to dementia and she is almost completely bed-ridden, except for a few hours a day when she is in a special wheelchair. She spends 90% of her time in her small room just looking out the window or staring at walls. She grew up on a farm with horses and those are now some of her only memories. I have been searching for awhile, but can't seem to find any. If anyone could help, I would greatly appreciate it.
