How can I create this effect?

[daniellemarie]

Hi,

I'm hoping someone can help me! I am trying to find out how this vintage effect has been created on this logo? I have been asked to create a logo for someone using an effect similar to this one but am unsure of how to re-create it?

Also, does anyone know where I can get similar floral roman vectors like the ones used in this image?

Thank you,
Danielle
