Is this postcard a mail out or do you want a double sided postcard?

Hi! I would love to participate, but I and other designers don't participate in non guaranteed contests because of all the usual characteristics that those clients have, we know that guaranteed projects means that the client is committed
to finding the right design and is willing to guide us in the direction their looking for other than non guaranteed clients
who don't give any feedback or give plenty of feedback then retracts their payment in the last moment.

It will be front and back postcard

Hi, this is my second time doing this. Of course I'll pay for the postcard design that I like it. I already submit the payment.
