Vintage Typography Camp Poster

I'm seeking a creative designer to craft a poster-sized (11x17) vintage advertisement for a children's camp. The design should be typography-focused with maybe some artwork, capturing a playful and fun tone. This will not be used as an ad, but is a gift for a Grandma who took her grandkids for a week of "Grandma Camp". I'd like it to include a picture of the kids.

Requirements:
- Vintage advertisement design experience
- Strong typography skills
- Ability to convey a playful and fun tone

Ideal Skills and Experience:
- Graphic design proficiency
- Experience with vintage styles
- Creativity in typography and layout

Please provide a portfolio showcasing relevant work.
