I obtained these in 1994 for a Starlog store.  These are leftover inventory from when the store closed suddenly.  They are all in postcard sleeves with backings.
Kirk with the background leg is no. 105-118, 1991, with some sticker removal residue over the barcode.
Kirk side look is 105-134, 1991.
Kirk as a Romulan is 105-307, 1993.
Kirk from the Paradise Syndrome is 105-311, 1993, with sticker residue over the barcode.

The Mugato is 105-302.  They should have set the phaser to stun.  Poor Mugato.
The postcard set from The Undiscovered country, all dated 1992, is -

The Deep Space Nine promo cast photo is 105-255, 1993.
