I’ve recently had QSL cards printed up by fdsQSL.com and was impressed by the service and cost (£29 for 200 inc. postage).
I asked for two QSL cards to be drafted and received the proofs from fdsQSL:
I found it really hard to choose between the two but in the end i felt the first one would be of more interest to a foreign amateur and is easily recognised as London.
If i make a QSO with you on the bands then feel free to request a QSL card 🙂
