Some designers and all non designers weren't familiar with the term "Counter," which among the many terms in typographic anatomy is perhaps the simplest to explain as any fully enclosed space within a letterform. Uppercase A, B, D, O, P, Q, R and lower case a, b, d, e, g, o, p, q and the numbers 4, 6, 8, 9 and 0 all contain counters. And let's not forget the & ampersand. Or as i said to a type challenged friend, it's the hole in the letter.
Set in Futura Bold, a geometric typeface designed in 1927 by Paul Renner for the Bauer Type Foundry. Printed in grey and white on a on a 100% cotton ribbed tank top.
