Being a devotee of both The Beatles and Trek, I was delighted to come across this! What a magnificent crossover of TOS and Yellow Submarine! I appreciate that the artist included Chapel and Rand. If you look closely, you can see and alternate submarine Enterprise in red with Evil Kirk and Spock there! Other clever mashups here: Harry Mudd as a combination Young Fred/Snapping Turtle Turk, a Klingon vessel as The Dreadful Flying Glove, and the Mugato as a Blue Meanie. I don’t know who made this but it’s brilliant!
