1935-D Fr 1613N G-G Block Only from 18 subject sheets?
The PMG Registry shows the GG block in two occurrences of the $1 Silver Certificate set
1935D $1 Blue ADD BP#! Clark Snyder GG 1613N
1935D $1 Silver Certificate '18 Subject Sheets' Fr. 1613sub18 (GG Block) 1935D $1 Blue Clark Snyder GG 1613sub18
My understanding is that there were no Narrow 12 subject sheet notes and they were all from 18 subject sheets
Has anyone seen any different details on the GG block printing for 1935-D Naroow variety?
