From what I can find online, this tie tack/lapel pin was produced by GULF oil in 1968.  There is a left facing elephant head (with raided trunk) over 2 connected horseshoes (open at the top to catch good luck).  I am guessing that the pin is pot-metal with a gold-tone finish.  It measures 3/4" wide x 5/8" high and is in nice condition.  The pin is a clutch style.

I have tried to describe any issues with this item as much as possible.  I can post additional photos upon request and will try to answer any questions you might have that weren't addressed above.  If you want to purchase more than one item, let me know and I will wait until your purchases are complete, then I will send a single invoice with one shipping charge.
