T-Shirt Surft Design

I am looking for a creative surf inspired designs for my t-shirt company. I need vintage inspired graphics. Please do not use other sites designs or use designs that are identical to other graphics on the web. The design needs to be unique, surf inspired, sailing inspired, paddle boarding inspired, and most importantly it has to be yours. I understand that other graphics can have a similar flavor but please keep it unique to you as a designer. My goal is to start with one design but can develop to about 10 to 20 designs. Again, it must be unique to you and it has to be vintage inspired. Similarly for what I am looking for can be found at shutterfly.com. Thanks
