O.k., so I was looking at the back of my dolls neck. ALL of them, including Nellie, say pleasent company on the back. However Samantha (1998), Felicity (2003) and Addy (2004) all have the name in all capitals and it is deeping impressed and more noticable. I actually had to serch to see where Nellie's neck says Pleasent company, because it is much smaller, it's says Pleasent Company as apposed to PLEASENT COMPANY, and it is not as deeply pressed. Hmmm....
Also, the earlier Felicitys have redder hair and softer eyes.
