"My Little Pony" lot of 4 / 3 stamped 1981 = 1st year / collectable vtg. toys

This lot includes 3 MLP's stamped '81 and 1 MLP stamped Greenbrier Int'l Inc. This was part of an Estate Box & I know nothing about MLP's - I have not cleaned them nor have I attempted to fix any hair, but I understand that's doable. The plastic on all 4 is in great shape.
