Well it actually depends on the amount of the stamps. I believe 44 cents is the correct amount of money needed to mail a letter like that. I would use 1 regular stamp, and 1 2-3 cent stamp.

You only need one!
it cost .26 cents
One 28 cent stamp will do the job if you are mailing your card from within the US.
TWO US Forever stamps will suffice (USA to London post card)
usually none, but if it needs a stamp, just one stamp is needed.
No you cannot use US stamps. Items mailed must have the stamps of the country of origin on them. Most shops will be able to provide you with the appropriate stamps to use to mail with their cards, or visit their post office!
To where? to the UK it'd be one second class stamp. to europe is 2 first class stamps,,,,,,it all depends on getting a grammatically correct question.
In the US there were 7 cent stamps printed. Many of the definitive series of stamps included all denominations from 1 to 20 cents and then every 5 cents after that. And the Postcard rate for part of 1975 was 7 cents.
typicaly 2 stamps
If this is just a post card you will only need the one stamp to mail it within the US.
