Maybe, although it does not appear to be as angular as the seven in box 7B. And there appears to be a cross at the midpoint of the down stroke although that may be a fold in the paper.
Also this is the first BC I’ve seen where the code in 12b doesn’t match the code in 9.
Verna Lee initialed the correction of the misspelling in the box 16 (looks like on June 22nd)but not the struck out Colored in Box 9.
maybe she didn’t strike through “colored”, and only initialed what she did correct personally.
Often people put a mark through the down-stroke of a number seven if it seems as though it might be able to be mistaken for a different number. Some people I know always do that to every 7 they write.
