Ever since I was a little kid I loved My Little Ponies released by Hasbro. I had tons of them plus stables, accessories etc and one of my favourites was Ringlets from the Brush N Grow range.
The ponies that were releases in the 80's were known as G1's, then they stopped production until the late 90's and released a new line (not too nice) known as the G2's and then again in 2002 another line known as the G3's. I think the 1980's produced the best ponies. I didn't like the G2's at all and am starting to warm up to the G3's. Most people who are into MLP probably have seen the cartoons, which are just so cute and friendly, great for little kids.
There are a few Collector's Books released and I have both of them. They cover a large range of ponies and have a price guide plus ifo like what each pony belonged to (range, family etc). If anoyone needs to know what the name of their MLP is then drop us an email and I'd be more than happy to help you out, but the books only cover the G1's and a few G2's.
I don't have a favourite MLP but I sure do like the Unicorns, they are absolutely adorable!
