Richard Bong P-38 picture question

Does anyone know the story behind this Life Magazine picture of Bong and a P-38, painted with noseart as " Marge " ?  I don't think it is the real one  ( 42-103993 )  Could it be a stateside plane with noseart added for something like a War Bond Tour ?
 
1.  " Marge " is in an Old-West block type font.  On other pics of the aircraft, it is in a "handwriting " script.
2. No kill markings.
3. No A/C number on nose.
4. No red paint on nose tip.
5. Prop spinner tips do not appear to be painted red. ( Behind props may be painted )
