I'm glad you like the logo. I've tried different color variations. I'm still looking at some fonts for the tagline and I'll upload them shortly. Let me know what you think so far.
I've also tried a few fonts for the tag line. When you mentioned that you wanted the font to be from the period of the movie were you referring to the 1960s show or the mid nineties movie?
I've made a few variations on the font of the tagline. I think it's hard to make the timeline of the logo across for someone in the general public. If I were to use a font that could definitely be tied to a specific time by the people who see the logo, then I think it would appear too campy and would not work well with the rest of the logo. So I've used a few fonts that don't draw attention away from the image and are not too flashy.
The font used in #72 is a vintage type of font that I think works well. From the new variations I think #83 works as well. It's a casual font, but not too much for it to be a distraction. Another one that I like is #82 which has a modern look yet still retains a bit of a retro charm. For a thinner casual font I prefer #84.
I think my preference lies with either #83 or #84. #79 although has a nice font I think it maybe feels a bit old fashioned and not as casual compared to the other two.
Both fonts have a casual feel. #83 feels more "fun" due to the irregular lettering, while #84 has a fun, but quieter look. It depends on how much emphasis you want the slogan to have. #83 pops a bit more, but do you want a more subdued look like #84 or something more "in your face" like #83. Something to think of is how do you want your clients to perceive you since the text of the slogan and font I feel gives across a bit of your personality, so that's why you should choose the one that you think describes you more correctly.
