Way back about two summers ago, I found this bag of, what I think to be, union buttons. I loved the colors..they were dated...and had great graphics. Now what do you do with cute union buttons? I glued them on to a large button and added velvet cord and what a fun conversation necklace.
Upon doing a wee bit of research I think the "I.B.T.C.W.& H." means, International Brotherhood of Teamsters, Chauffeurs, Warehouse men and Helpers of America. Interesting huh? I suppose you got a button each month. The number is the local organization.
I don't know much about this...but, I do know, the graphic artist was a forward thinker! Kudos to that person or company!
