Alvin is one of the elves from Santa's workshop. He is holding a toy train in one hand and a wooden mallet in the other.
This 2003 poseable figurine is from the Boyd's Collection Shoebox series. The registration number stamped on the base of his shoe shows he is a first edition piece and he measures 4.5" tall.
There is a little light scuffing in places, which can be seen in the pictures, but nothing of significance.
