Yes! But please read our logo usage policy.
TL;DR is that any of the graphics in our PyLadies assets repo can be used for local group promotion and/or to show your support.
Logos used with the intention to sell merchandise, please seek permission from the PyLadies leadership.
There is "official" merchandise sold - with proceeds going towards PyLadies - at our own spreadshirt site.
