Star Trek TOS Declaration Class

Rummaging through some stuff my dad has from the 70s for Star Trek, I found a design for this Declaration Class. Found it interesting for two reasons. One, it's a variation on the 'Enterprise was designed upside-down' as Jeffries originally designed it, probably closer to how he originally designed it instead of the 'Pegasus Class' I had designed. Two, the Declaration Class was the ring ship design that was used as an earlier, pre-TOS Enterprise when it wasn't approved for the main show. Anywho,
