Booth signature for sale

[NJREB1863]

Looking beyond the "JWB" signature just sold and looking at the words written above the signature, those words appear to be in the same hand as the signature and read "by my hand and". If you look at the a's, in the words "hand" and "and" they are both open on the top. Compare those a's to the "a" in the word "lady" in the authenticated signature below that Dave posted, the "a" is closed and looks nothing like the open "a". I find it hard to believe that HA wouldn't have an "expert" on staff to authenticate this signature, but I now DO believe it looks suspicious at best after looking at it a few dozen times or so!
