Joe W., I have no exemplars with your listed salutations. These are my oldest exemplars and I have no opinion on authenticity. I only have 1 Travolta and I THINK he drew an airplane on top of his name. The blue card is said to be from 1978. Other 2 unknown dates. Hope this helps.
Thanks, David. Your early examples clearly display is signature evolution. The one I am asking about must be somewhere in between. Although, keying off the ending of his last name I see the same characteristics as your vintage signatures.
Joe W., His career took off with "Carrie" in 1976, so yeah, yours must have been the next evolution of his autograph. those 3 were the only examplars I had with a visible bow tie at the end of Travolta. If I were a betting man your Travolta is "talking to me". All the best.
