Oh, for heaven's sake either just do it (at the mall if you like) or don't.

I would expect my Realtor to advertise online; Trulia, Realtor.com, Zillow or similar webpage(s).
Advertise in local Realty magazine,
Print colored flyers for box attached to prominent 'For Sale' sign.
Invite other Realtors for 'open house'.

I have not heard of passing out cards!

Why do the work you are paying a Realtor to do?

I'm confused a little! Many realtors get clients by word of mouth. I have referred my own many times to my friends and newcomers to the area, having some cards to give them is a big plus! What exactly is on the little cards? I've seen lots of sale ads on facebook and other social nets.

I can understand the real estate agent giving you a few cards to keep handy in your bag, but I would think it's really up to him/her, not you, to spend the time to get the word out on your house.

To sell your house, you must get the word out to as many people as possible.

Even though "all your friends" know you're selling, *they won't always remember to tell their other friends/family/church people/work chums*.

& if they do remember, the friends, etc likely won't remember your address or your agent's name, etc.

Any kind of "visual aid" is helpful, & anything you can do to facilitate the sale will be in your best interest.

Pass out those cards at work & at church, give 'em to the waiter at the restaurant & the cashier at McDonald's (she has parents & teachers & aunts & uncles)...

I once had an agent who paid a toll at the "change made" booth, & she handed the toll booth guy a card.

She sold him a condo.
