Letters Home WWII (1)

Dad had been stationed in Australia for about 10 months when he wrote this letter. It's postmarked 8 Sept 1942 just 3 days after meeting Mum for the first time.  Of course the mail was sent from here to San Francisco and then mailed from there so I have no idea when he wrote the letter or how long it took to get to the US.
The condition of the letter and envelope is perfect.  All his letters had either a censor stamp or seal on them.  So glad Grandma saved these letters.  Unfortunately the ones he received from Grandma and Mum have all been destroyed.
