Looks like 2013 will be colorful, judging from Tribes 131’s calendar. From 10 a.m. to 6 p.m. Saturday and noon to 5 p.m. Sunday, the gallery at 131 24th Ave. N.W. in Norman hosts its 19th annual calendar signing. With the American Indian artists’ signatures, the months become that much more valuable! Calendars are $15 each. Call 329-4442 or visit tribes131.com.
