[Dx-qsl] New style IRCs vs. Old Style IRCs

[Tom LeClerc W1TJL]

OK folks, I have a question.  New v.s old style IRCs.  What is the
real difference??  At my local post office there doesn't seem to be a
difference.  They take them both for 1 first class overseas postage. 
Couldn't find anything on the USPS website about it either...
