Was this US 62 Texas shield ever on the road?

In this hobby, you never know when you may find something interesting, and this past week was no different. Earlier this week, I had traveled to Memphis for work. Staying downtown, and that it was my first time in the city, I headed to Beale Street and ended up going to the Rum Boogie Cafe for live music and something to eat. The ribs were very good and the music by Fuzzy Jeffries and the Kings of Memphis was even better.

However there were two old US Highway signs on the stage that caught my attention. One a US 61 shield - standard. Also of interest was an old bumper sticker on the US 61 shield that read "4 Lane 61 Now!" But it was the US 62 Texas shield that caught my eye. It was more unique than the standard US Highway shield and made me wonder if it was a legitimate highway sign or a great design.

I have a closer look at the shield below.

Now, US 62 does go through Texas. However, when you look at the highway sign gallery experts at AARoads, Texas never used that style. So, that makes it seem likely that it wasn't ever on the road. However, there's something about the design that is unique and not found that it could certainly have been a test sign or briefly used. Doing some additional research, I did find another angle of the sign from the Rum Boogie Cafe's website.
