Letter from UK to USA

[DanW]

Hi all, I want to send 2 photos from the UK to the USA, I would like the photos signed and returned not using an irc and instead using us stamps, please can you tell me how many US Stamps, also which ones I will need for someone from the USA to reply back to me in the UK.

Thanks in advance

P.S. I will send the letter to the USA at my post office and wanted to know how many us stamps on my sase are needed

if it is a large envelope you will probably need 5-6 forever stamps, a regular envelope you need 3 forever stamps (or 2 and 1 10c stamp)

3 Forever stamps will be fine for an A5 envelope. Not sure about an A4 envelope, but smanzari's suggestion seems likely.
