Sherlock Valentine's Day Card #1 Sample

So this is a little Sherlock-y Valentine's Day card design thing that I made.

I just set up a PayPal account and I've got my debit card checking banking system thing all done up so that's a start. I'm still trying to figure out the ins and outs of the site in terms of transactions and stuff, but if I were to put these up for sale:

A.) Would people be interested in buying one for their sweetheart this Valentine's Day?

B.) What would be a reasonable price for one of these?

If people are interested, I'll show an example of what the card'd look like if you bought one.
