The shirt or hat or something else would have my name on it in graffiti?

I don't want what's 'in fashion' like they sell in big chain shops..I'm looking for retro style hats. 30's/40's/50's etc. Is there anywhere in the UK or online.

is there any way i can get custom New Era Hats. i wanna know if there is a place to call or a website that can do this for me the new era site doesnt say anything about custom hats

This custom seems to have lost relevancy in todays Western society. It appears that it has been observed primarily during the last 100 years only as a token of politeness.
