tattoo ideas annyone?

My boyfriend and I are getting tattoos together. The idea started out that I wanted his initial E on my neck in a cool font and he wanted a shield with the letter M inside of it on his lower inner arm. I then had an idea of getting a locket or lock of some type with the keyhole looking like the letter E and he would get a skeleton key with an M on it. Could anyone possibly send me any images or links to get visuals for this idea? I want to use black ink only and have an antique romantic feel. Thank you so much to anyone who can help!

bad idea. i cant tell you how many initials ive had to cover up. there are other ways to show someone your love and dedication to them.
