...posting this composite of zero x 4 because the next comment is going to be 'but that's David and Mark' - but it's not David and Mark, there never was a David. And if the younger boy is zero, then the older boy can't be Mark, because Mark was born in 1965. David only exists in the myth because they had one boy too many.
The fact that baby David (upper right in the grouping of 4 pics) closely resembles young Barry (the other three pictures), but with David having obviously longer original baby hair at age 2. This excludes them being the same baby, IMO, as father of nearly bald babies at age 2. The resemblance goes to support the narrative in the 1961 FOIA INS docs that BHO Sr could be the father of Barry.
Ruth Baker says that BHO Sr. is that father of both Mark and David, IIRC (haven't double-checked Maraniss' interview with her, yet).
Hopefully, Zullo, Arpaio and Corsi will dispel any delusions that anyone other the Stanley Ann is Barry's mom tomorrow as they also identify the father as shown on a found original LFBC (the missing page 11 from the divorce docs, per speculation by Fogblowers).
