I made this for a notebook cover. I laser printed it on a full-sized shipping label at my local office store, rounded the corners, and applied it. It made a rather nifty cover. I may do more of these.
For now, here is the image I used.
Just about all of the images used are in the public domain, printed on or before 1923. I used Photoshop brushes that were created after 1923 and are covered by personal/fair use.
I saved this as a png at 32 bit depth, but if memory serves, I believe I made this at 300 dpi. The next time I open the psd file, I’ll take a look and note it here.
Update, 05 Mar 2016:
It’s 8″ x 6.5″ and at 200 dpi.
