Weddingbee boards

I'm working on designing our response postcards, and I have the back part pretty much finished, but I am really stuck on what to put on the front. I have tried to find an actual vintage postcard to use, but haven't come across anything that has any special meaning to us, so they just seem too random.

We are getting married in Tulsa, OK - my fiance is from a farm town in Kansas and I'm from Houston, TX. I've thought about using a combination of postcards from our hometowns, or maps, etc. but I think it will be cheaper for printing to just decide on one image to use for all of them.

The bull is actually a photo I took at his parents' farm. I have tons of pictures from the farm, but I don't know what to choose! I know that bull picture is a little silly, but our wedding is going to be laid back with a rustic vibe, so I think it could work. I like the touch of humor. (Also, our venue is a lodge and they have longhorns that live on-site so it kind of ties in.)

The other version I've been playing around with is a vintage picture of downtown Tulsa that I found online. My fiance likes that one (I haven't shown him the bull yet), but I'm not in love with it.

Has anyone else DIYed response cards inspired by vintage postcards? How did you pick a photo to use? Any other ideas for ours??

I love the bull!! RSVP NOW or else :-)

Thank you guys for all the feedback! I am definitely leaning towards the bull, as long as my fiance approves.

@DeaconBride - I had the same thought about trying to make the back go with the bull a little better. I did the back first and used the butterflies, etc. to tie it into the rest of our invitation suite. I don't know if throwing in bull horns or other similar elements just on the reply card will make it seem too disconnected from the rest of our paper pieces. I'm still brainstorming on that one, but I definitely see what you mean.

Here is my invitation design (we're getting them letterpress printed on brown chipboard)

p.s. If anyone is looking for an affordable letterpress printer, email Gary at Letterpress Chicago. They quoted me about $150 for 100 invitations - I don't know if they're so cheap b/c of the chipboard or the size or what, but I am so happy to have found them!

Also, for anyone DIY-ing invitations - I found a lot of the elements I used in our design for free at Vintage Vectors and Wikimedia - both are great resources.

oh, one more awesome resource for free graphics - fuzzimo! I got a bunch of hi-res old postcard images and paper textures that I pieced together for the back.

Do you guys have any ideas for more quirky wording on the "Accepts" and "Regrets" part? I looked up a bunch of ideas last night, but none seemed to fit our theme.
