I have a set of three of Anek's prints in my kitchen at the moment - I adore them! And she's a treasure to order from. :)
If you like Pyrex or canning, Erinink does adorable little prints. Plus, she's very sweet.

I really like the 1st one but I have mermaid prints in my kitchen! :oD
Whoa, $125 for thrifted frames, a little paint and line drawings? Sounds like a good DIY project to me.
I like the pie & egg photos.
I have vintage fruit crate labels framed and hung in my kitchen, along with decorative bundt pans, and a collection of vintage cow creamers on display. And I just ordered vintage-style tea towels with fruit designs on them to make into curtains. It all makes the kitchen so colorful and cheerful.
Like Jacks_mama, I have framed vintage fruit crate labels in my kitchen. I'm originally from a fruit growing area (historically, not as much anymore) and was able to find labels from my home town and surrounding area. I was even able to find the label my grandparents shipped under for years. Its a nice way to bring a piece of my hometown and family history into my kitchen, even though I'm hundreds of miles away. I found mine here: http://www.thelabelman.com/ It has more than just fruit labels if you're interested in seed packets or other vintage advertisements for agriculture.
Another one to add to the round up!
I have a fun one from Society 6 called "Let's all go and have breakfast." It makes me smile.

I just ordered the Anek print. Can't wait to get it!
If you like photos like the pie and eggs, a cheaper option is to buy an image off of a stock photography Web site. Similar look (real life photography) and you can pick which image you like best.
Here is my favorite pic in our kitchen, Lettuce Turnip the Beet
The other favorite in my kitchen is the mapping of over 100 tools used in the preparation of delicious food
Can anyone remember what I'm thinking of- a while back the site showed off a really cool graphical image that was a giant print like a pie chart and had ingredients listed and percents of the chart for how to roughly make any kind of batter- muffins, pancakes, cake, cookies, etc. It came printed in a few colors I believe and was SO cool and I can't find it anywhere.
