a.k.a. Unauthorized Short Log Mug
This is a mug shaped like a rum barrel. Manufactured by Mornsungifts and later sold through Oshi (Australia) and barproducts.com (US). The original version was manufactured by Dynasty as a "Short Log Mug" but this is an unauthorized version with lighter glazing and no marking on bottom that was sold on e-Bay and through several wholesale bar supply stores online.
