Just saw this on the bay and it doesn't look right to me. I may be wrong, but if it is an escher it is the only one with those specific dimensions I've ever seen. The scratches on the sides are also weird. Never saw one like that. Not to mention the thickness. The seller doesn't say what it is but it looks kinda skinny to me. :thinking:
