Trust me, it’s not that important.

Please don’t ruin your sale by adding serial numbers that don’t belong! Even though this is an authentic Diana, it will not pass as authentic because of the tampering. The bag’s details belong to a much older series Diana, max 28XXXXX. Please understand ( to all these types of resellers) a missing serial number sticker, card, or even both on vintage bags don’t make a lot of difference in evaluations; about $200 lower, that’s all! You don’t have to do that to increase the value. Please don’t do it, trust me, I WILL KNOW!
