TCMA was ahead of its time, as evident in this advertisement from the June 1978 issue of The Trader Speaks, which offered a subscription to their 1978 Minor League card sets.
You also got to pick from your choice of a free 1975, 1976, or 1977 set when you signed up.
Based on TCDB’s archives, it looks like TCMA printed at least 27 minor league sets in 1978. A few of the bigger 1978 TCMA minor league cards were the Knoxville Knox Sox Harold Baines, Tidewater Tides Mike Scott, Greenwood Braves Brian Snitker, and the first card for hobby favorite Rusty Kuntz.
