here you go..
My most recent (last year) and my very first one (14 years ago) are on the same arm. The new one is a mighty mouse with my fathers initials/ the initials of myself and 2 brothers. All 4 of us have the same one. The sheet music arm band is the opening guitar lick from johnny b goode. others done: arm has a guitar and some notes and stuff. have a small piece on my left pec and one on my right shoulder i got with my wife when we got married (no names, just a nice memory to share ).
Its a personal choice to get them. If you want one, cool. If not, no biggie. like sylvie said earlier the sensation of getting tattooed can be great and can be a little addictive. Some folks are into that, others less so. Nothing i have can be seen if i'm wearing a polo- basically for professional reasons nothing past the 1/4 sleeve mark. The ones i got arent for showing off to other people, i got them for me.
If you want one, my advice is - get a good artist. That counts. Never buy a tattoo- hire a good artist. Look at their portfolio and body of work. Any real artist will happily share their album with you. Stay away from discount shops.
