When you were a little kid did you or your parents write your initials or name on your toys? My mom did this occasionally with toys that were brought to school for show and tell (so they didn't get mixed up with other kids things), and my sisters and I marked our My Little Ponies on the bottom of one hoof with our first initial. I still have all my ponies, and it is easy to tell my childhood ponies apart from any of my other collection ponies or ponies I am in the process of selling because of this.
However, sometimes toys go astray - sold at garage sales, left at friends houses, donated to thrift stores. Do you ever wonder where your childhood toys are now? Since I buy and sell vintage toys and kids books I think about this quite a bit. Who was the original owner? What kind of adventures have these toys been on? Did this toy have a special nickname?
Someone on the MLPArena posted about a project she is working on that involves marked or initialed My Little Ponies. It is a website that has pictures, descriptions, and locations of marked and initialed My Little Ponies. If you are looking for a child hood My Little Pony, and initialed it you can look in the database and see if you can find it! Right now there are just over 60 ponies listed. It isn't a lot, but hopefully it will grow.
The website project is called "The Toy Loft: Where in the World is My Childhood Pony?" and can be found at this address: http://thetoyloft.com/wwcp/index.php
I dug around in the boxes of ponies I have for sale and found four marked ponies. I submitted these four to the website:
