While I am certainly no expert and have purchased good ETs and bad ETs I will offer my humble opinion. The picture is rather odd and almost doesn’t look like her and the signature looks to be on some sort of framing board. I wouldn’t buy it (which doesn’t mean anything) just because of its look however it looks like her E, very much her E. If you look at some of the cead examples it looks exactly like her signature. How much is it and where - I didn’t find it on EBay - hope others will comment on this.
