Notice the difference between this London Rollergirls patch and this one.  Aside from the other looking more metallic (which be a product of the flash), this patch has less detail around the letters. For example, look at the second "L" in Rollergirls.  This patch features the letter on a white background with no border.  The other patch has a black border around the white background.

• Lutece Destroyeuses Roller Derby Paris

Lutèce Destroyeuses Roller Derby Paris alternately spells and does not spell their league name with an accent on the first "e".  They are registered with WFTDA with an accent, so I have chosen to record their league name this way.
