It's a possibility it could be a comic gift, however it's not one I have documented. I don't think I have ever owned the clip, and I had the comic up until at least 188 and also the Friends one to around the same time (I'm not sure exactly when I stopped, but I still have my original 188, so can date it at least that far!). Of course, it's not impossible I had it and lost it or something. There are still some things missing (I swear there is another Barbie box in the loft that might have some things in it)
139 had a Best Wishes card, 144 was gift labels, 183 was a pony bride sticker, 191 is a heart bead bracelet and 164's hair slide was a princess comb (incidentally I must have got that, but only ever remember having one princess comb... although now I think about it I was convinced mine was long gone and one magically reappeared).
176 is a maybe though (we have at least two with tape on the front, but no gift, and no idea what it was, and there's a few after 200 I'm not sure about. Some I'm not sure about with Friends as well though, so there are some possibilities.
