Hey Dude.
This is the exactly correct place to post this. In 1979, Norlin, the then owner of Gibson, Epiphone and other brands, moved Epiphone production from Kalamazoo, Michigan, USA to Japan.
We see some "Epi" branded models showing up here from time to time. I don't know a lot about them, other than they are another Epiphone derivative.
Thanks for showing a clear picture of the label. This type of label, larger and squarer than the earlier blue label, A label of this type was used on later Japanese, Matsumoku made 'Epiphones'. Epiphone Marketing operations moved to Lincolnwood, Illinois, USA in about 1975. So we may deduce from this that this 'Epi' label places this Taiwanese guitar in the mid to late 1970's
Where are you and this Epi?
The label you show appears to have a hump in the middle of it. This usually means the label is affixed over an vertical brace which holds the splice of a two piece back. If you could zoom out we could see if this guitar has a two piece back. Or, can we see a picture of the back.
If this has a two piece back, this would indicate it is a more expensive model. Most cheaper guitars have a one piece back without the vertical brace.
Could you get us a couple more detail pictures?
Read the "A Brief Epiphone History" thread I just created. There is a notation at the 1983 time frame that some Epiphones are being made in Taiwan and Indonesia. He is not real specific as to whether this is the beginning of production in the South Pacific. This could put the beginning of the 'Epi' line as late as 1983. In 1985 or 1986, the Gibson Guitar Corp. we know today was formed. This MIGHT indicate the end of this brand.
For all intents and purposes, it appears to be a re-branded Epiphone FT145. While it is possible yours is a 1979 / 1981 year of manufacture, I'm guessing it is newer than that. That is just a hunch, based on the tuners and label. If I had to hazard a guess, I'd say no older than 1975 to mid-1980s.
Could you get us a picture of the guitar's back?
