Misplaced 307th Bm Gp Mission Chart

For what it's worth to anyone interested in 307th BG, the attached chart image file states "Eten Island", "Mission 237" and "307 BG".  It was included in pdf versions of microfilm files for 11th Bomb Sq. (M).  It was in negative format (white lettering on black) and I didn't notice it didn't fit 341st Bm Gp until I had converted to positive format (black on white).
