Cheinco Housewares advertising trays

Have trouble telling new from old advertising trays? One of the ways to eliminate a good number of new trays is to be familiar with the names of new manufacturers. One of those, Cheinco Housewares, has a distinctive trademark that makes detecting their new advertising trays and signs easy. Their log cabin style mark (Fig. 2) is 3/8" high by 1/2" wide. It appears in the rim of the new Clysmic Water tray in Fig. 1.
