This 24-card standard-size set was produced by MSA (Michael Schechter Associates) for MooTown Snackers. The cards were inserted inside 5 ounce and 10 ounce cheese snack packages. It is reported that more than two million cards were produced. Collectors could also obtain the complete set through a mail-in offer. The cards obtained via mail did not come with the mali-in offer tabs. Cards with tabs have twice the value of the prices below. .
