This week's featured shaker are green sitting bulldogs. They have been found in orange and yellow as well (see photos below).
These are very little sets measuring less than two inches in height. They were made by Goebel in Germany and designed by Arthur Moeller in 1925 according to the McHugh's Goebel Salt & Pepper Shakers reference book.
They should be marked with either the pre-WWII impressed Goebel crown logo and/or impressed with the mold mark "P479".
