To honor the work of New York City public school teachers, who give their students what he calls “the best public education in the land,” retired educator Marty Raskin has been amassing memorabilia that may remind city educators of their own school days — and surprise them with curious artifacts they’ve never seen before. At a ceremony in the lobby of the UFT’s Manhattan headquarters on Dec. 17, Retired Teachers Chapter Leader Tom Murphy spoke of Raskin’s determination to display his collection. The memorabilia, some of which dates back to 1850, will rotate every three months in lit-up cases in the UFT lobby. “We appreciate that they’re here inside the teachers’ union now,” said UFT President Michael Mulgrew. The audience was mesmerized viewing Board of Education-branded baseball gloves, ornate doorknobs, lunchboxes, desktop bells, school pins and more. “It’s nice to see where we’ve come from,” said retiree Margaret Pointdujour. “I recognize so much here,” said retired teacher Linda Pearson, taking it all in.
