Who is this Peterson, and why are his squares so perfect? That may be a question to which we'll never get the answer, but one thing is certain—that Peterson sure designed a great tile! The perfectly smooth center square is surrounded by a perfectly straight square, while that square is surrounded by a square that looks like satin ribbon perfectly threaded through delicate lace. Finishing it all off is a perfectly dimensional raised border decorated with fancy scrolls and beautiful fleurs de lis. Like Mary Poppins, the 2422 Peterson's Perfect Squares tin ceiling tiles are practically perfect in every way!
