Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

This is by the late great OIC member Jack White. He is speaking of Altgens photos, all of them. 

In Trask we learn that negative numbers did not correspond to the photo
numbers. 

First exposure...negative 2 (vertical shot motorcade on Main)
Second exposure...negative 3 (horizontal shot motorcade on Main)
Third exposure...negative 4 (limo turning from Main to Houston)
Fourth exposure...negative 5 (limo half way down Houston, from rear)
Fifth exposure...negative 6 (limo coming down Elm, JFK hit)
Sixth exposure...negative 7 (limo heading to underpass, Hill on trunk)
Seventh final exposure...negative 8 (pedestal, man in hat, Hesters)
