Please provide me with the context or topic. "Sign with last name and established" is too vague to write a blog post about. I need to know what kind of sign you're referring to (e.g., a business sign, a signature, a street sign, etc.) and what "established" means in this context (e.g., a business's establishment date, a signature's legitimacy, etc.).
Once you provide more details, I can write a well-structured, SEO-optimized blog post that addresses the topic.
