monsieur_champs has asked for the wisdom of the Perl Monks concerning the following question:

I'm trying to make an "official" t-shirt for the São Paulo Perl Mongers and I would love to keep some visual identity with the Perl Mongers logo.

My question is: anybody here can tell me the font family or font name for this Perl Mongers logo?

And anybody here can point me any visual presentation recomendations (or rules) so I don't mis-use this logo on São Paulo Perl Mongers t-shirts?

Many many many thanks in advance and may the gods bless you all.
