Strap-On Art

This is annoying! I feel I should be able to identify the artist but can’t! I’ve stared at the obscure signature until my eyes water but no help. Image search didn’t help me either but I’m probably not doing it correctly. Help?
And thank you Untipo who identified the artist as Shpanktank!
